Description

Intestinal clamp

Technical Field

The utility model relates to an intestinal clamp in the technical field of medical appliances.

Background

In laparoscopic surgery, especially in full-cavity surgery, the intestinal tract distance needs to be measured when the stomach and intestine are anastomosed, and the method currently used clinically is continuous visual estimation and cannot be accurately measured. For example, total gastrectomy, Roux-en-Y esophageal jejunal tract reconstruction, requires transection of the jejunum 15cm below the ligamentum Quersonii, proximal-distal jejunal side anastomosis, with the bridge loop at a distance of 50-60cm from the distal jejunal opening. Clinically, a doctor can only visually observe the distance of the bridge loop by 5cm at each time, errors exist in each visual observation, the starting end of each measurement cannot be marked in the measurement process, the continuity of the two measurements cannot be guaranteed, and errors can also be caused. The longer the distance is measured, the more times the measurements are made and the greater the accumulated error. The error of measuring the distance between the bridge loops in the operation can cause great influence on the postoperative recovery of the patient, such as the occurrence of complications of reflux esophagitis, Roux-en-Y retention syndrome, malabsorption, malnutrition and the like, so the measurement accuracy of the distance between the bridge loops in the operation is very important.

In addition, another vigorously developed surgical type, namely weight loss surgery, in the abdominal surgery at present is also in urgent need to solve the problem of accurate measurement of the intestinal tract in the surgery. As is well known, obesity is closely related to the occurrence of type 2 diabetes, coronary heart disease, hypertension, obstructive sleep apnea syndrome and other diseases, and the fatality rate of patients is continuously increased. The poor compliance of most of the obesity patients to exercise, diet control and drug treatment causes the unsatisfactory effect of reducing the physical quality. The weight-losing operation can effectively reduce the body mass of the obesity patient and improve the metabolic condition. In weight loss surgery, the accuracy of intraoperative measurement of small intestine length is extremely important. The proportional detour based on the length of all small intestines is the development direction of the accurate surgery of the weight-reducing metabolism surgery and also guarantees the effect of the weight-reducing surgery. But face the same difficulties of laparoscopic gastric surgery due to the lack of relatively accurate measurement methods and instruments.

Referring to fig. 1 to 8, the intestinal clamp according to the embodiment of the present invention includes a torsion spring 20 and two clamp bodies, the two clamp bodies are a first clamp body 11 and a second clamp body 12, respectively, and the first clamp body 11 and the second clamp body 12 are hinged by an articulation piece. The articulated elements include articulated rod 40, and first pincers body 11 and second pincers body 12 can rotate around the axial direction of articulated rod 40 relatively, and torsional spring 20 cover is established on articulated rod 40 to fix a position torsional spring 20. The first caliper body 11 is provided with a pick assembly, the pick assembly includes at least two picks 30, the picks 30 are circumferentially spaced around the hinge member, and the picks 30 are made of a material with good elasticity, such as a light and thin stainless steel member which is easy to bend. The first end leg 21 of the torsion spring 20 is connected to the first caliper body 11, the first end leg 22 of the torsion spring 20 is connected to the second caliper body 12, and the first end leg 22 of the torsion spring 20 defines a fan-shaped track area to cover the pick assembly when rotating around the hinge. The clamp leaves of the two clamp bodies are provided with marking parts, and the measured parts are marked through the marking parts after each measurement, so that the starting point of the subsequent measurement is determined, and the measurement precision is improved. Optionally, the marking part is a marking pen 70, and colored dye solution harmless to a human body can flow out of the marking pen 70 to mark gastrointestinal wall tissues in the laparoscopic surgery, so that the marking is realized while the distance measurement is carried out, the measurement error caused by the peristalsis of the gastrointestinal wall is effectively reduced, and the probability of postoperative complications caused by low operation precision is reduced. The marking part is positioned at the end part of the clamp body clamp leaf so as to mark.

When the bowel forceps are used, a user holds the forceps handles of the two forceps bodies and closes the forceps handles, the torsion spring 20 is compressed, the distance between the forceps leaves of the first forceps body 11 and the forceps leaves of the second forceps body 12 is reduced, and when the second forceps body 12 rotates relative to the hinge piece, the first end foot 22 of the torsion spring 20 fixed on the second forceps body 12 passes through the shifting piece assembly. In some embodiments, the pulling plate assembly is located on a first end surface of the first caliper body 11, and the second caliper body 12 is hinged to a second end surface of the first caliper body 11, the first end surface and the second end surface being opposite to each other, so as to ensure that the first end leg 22 of the torsion spring 20 can abut against the pulling plate 30 when passing through the pulling plate assembly. When the first end leg 22 of the torsion spring 20 passes the pick 30, the hand of the user will feel a certain resistance, and the first end leg 22 of the torsion spring 20 will make a sound by dialing the pick 30, which may indicate to the user the number of the picks 30 that the first end leg 22 of the torsion spring 20 has stroked. When the user releases his/her hand, the elastic force generated by the compression of the torsion spring 20 pushes the second pincer body 12 and the first end leg 22 of the torsion spring 20 to move back over the pick 30.

Referring to fig. 2 to 4, in the present embodiment, the number of the shift plates 30 in the shift plate assembly is three, when the first end leg 22 of the torsion spring 20 crosses the first shift plate 30 and abuts against the shift plate 30, that is, is located at the first gear, an included angle between the blade ends of the two forceps bodies is 120 °, and a distance between the blade ends of the two forceps bodies is 8.7 cm; when the first end foot 22 of the torsion spring 20 slides across the second shifting piece 30 and abuts against the shifting piece 30, namely, the second gear is located, the included angle between the blade parts of the two forceps bodies is 60 degrees, and the distance between the end parts of the blade parts of the two forceps bodies is 5 cm; when the first end leg 22 of the torsion spring 20 runs across the third shift piece 30 and abuts against the shift piece 30, i.e. is located at the third gear, the included angle between the blade parts of the two forceps bodies is 30 °, and the distance between the blade end parts of the two forceps bodies is 2.6 cm. The first shifting piece 30, the second shifting piece 30 and the third shifting piece 30 in the shifting piece assembly are sequentially distributed towards the direction close to the clamp handle of the first clamp body 11. Because the plectrum 30 is spacing to the first end foot 22 of torsional spring 20, therefore when the first end foot 22 of torsional spring 20 and plectrum 30 butt, the interval of two pincers body pincers leaf tip is basically fixed to the accuracy of having guaranteed measurement and mark. In addition, when the first end foot 22 of the torsion spring 20 abuts against different shifting pieces 30, the distance between the end parts of the forceps blades of the two forceps bodies is different, and when the actual operation is measured, the shifting pieces 30 with different gears can be matched to measure different distances, so that the measurement precision is further improved. Taking the measurement of the distance of 58.7cm as an example, the first end foot 22 of the torsion spring 20 can be firstly kept in contact with the second shifting piece 30, 50cm is obtained after 10 times of measurement and marking, then the first end foot 22 of the torsion spring 20 is kept in contact with the first shifting piece 30, and the previous marking is taken as a starting point and measurement is carried out, so that 58.7cm can be obtained. According to the actual measurement needs of different operations, the distance between the marking parts of the two forceps bodies can be adjusted in advance when the first end foot 22 of the torsion spring 20 is abutted against different poking pieces 30, so that the requirement of accurate measurement is met.

Since the marking pen 70 can flow out the trace of the dye solution harmless to the human body to mark when in use, the marking pen 70 needs to be replaced when the dye solution is used up, in some embodiments, the marking pen 70 is detachably mounted on the forceps leaves of the forceps body through a mounting component, so that the cost for replacing the marking pen 70 can be saved, and the whole intestine forceps does not need to be replaced.
