Description

A percutaneous puncture intracavity traction and ligation device

technical field

The utility model belongs to the field of medical instruments, in particular to a percutaneous puncture intracavity traction and ligation device.

Background technique

Laparoscopic surgery is a revolutionary development in the field of minimally invasive surgery in recent years. It can be checked and treated at the same time, and it is one of the most advanced and cutting-edge minimally invasive techniques. Laparoscopic surgery is a newly developed minimally invasive technique and an inevitable trend in the development of future surgical methods. It is a modern high-tech medical technology that uses advanced equipment such as electronics and optics to complete the operation. Times progress.

Principle of laparoscopic surgery: Laparoscopic surgery is an operation performed in a closed abdominal cavity: the camera system, under the good cold light source illumination, takes pictures of the organs in the abdominal cavity on the monitoring screen through the laparoscope implanted in the abdominal cavity. Under the monitoring and guidance of the display screen, the physician manipulates the surgical instruments outside the abdominal cavity, and performs operations such as exploration, coagulation, hemostasis, tissue separation, incision, and suturing of the diseased tissue. It is a model of the application of high-tech technologies such as electronics, optics, and cameras in clinical surgery. Laparoscopic surgery is further divided into multi-port and single-port laparoscopic surgery.

Porous laparoscopic surgery method: Make three or four small incisions of 0.5 to 1 cm in the patient's abdomen, insert a trocar called "trocar" into each to create a tubular working channel, and insert laparoscopes and surgical instruments through these channels. The hands are not allowed to enter the abdominal cavity and all surgical operations are performed through these channels. Single-port laparoscopic surgery method: a 2cm incision is made through the umbilicus, and a "port" is placed to form a single-port channel, through which the laparoscope and surgical instruments are placed for operation.

Although the multi-hole laparoscope is convenient to operate, it has many abdominal incisions, many scars, and obvious scars; the change from multi-port laparoscopy to single-port laparoscopy is to reduce the number of abdominal wall incisions, so that the scars are more concealed and more aesthetically pleasing. One channel for surgery greatly increases the difficulty of surgery, prolongs the time of surgery, and increases the risk of surgery.

Utility model content

The purpose of the utility model is to provide a percutaneous puncture intracavity traction and ligation device in view of the current situation of the existing laparoscopic surgery methods, in order to reduce abdominal incisions as much as possible and facilitate the operation.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a percutaneous puncture intracavity traction and ligation device, comprising: a fixing bolt, a trocar, a traction rod and a traction wire;

The fixing bolt is a hollow cylinder, and a fixing rod is arranged in the middle;

The puncture device is a hollow sharp needle, and the top is provided with a hollow puncture force bearing seat;

The traction rod is a slender rod body, and one end of the traction wire is fixed at the tail, and the other end of the traction wire is in the shape of a wire loop. The wire loop is sleeved on the traction rod and the traction wire to form a coil. Free sliding on;

The traction rod, the puncture device and the fixing bolt are successively sleeved from the inside to the outside.

Further, the fixing rod vertically passes through the middle of the fixing bolt, and the center of the fixing rod is provided with a perforation of the vertical fixing rod; the puncture device passes through the perforation of the fixing rod.

Further, the center of the hollow puncture bearing seat is a circular hole communicated with the puncture device, and a sealing ring is arranged in the circular hole.

Further, the diameter of the trocar is 1.5-2 mm.

Further, the length of the drawbar is 20-50 cm.

Further, the length of the pulling wire is 15-45 cm.

When in use, the puncture needle is inserted into the fixing plug, and at the same time passes through the perforation in the middle of the fixing rod, the hollow puncture bearing of the puncture needle is located at the upper end, after the puncture needle is punctured into the abdominal cavity, the traction rod is inserted into the puncture needle, and the traction wire is It is located at the front end and enters the abdominal cavity, and then the puncture needle is taken out. Then, wrap the diseased tissue with a coil and then pull the traction rod to tighten the coil. At this time, the traction rod is located outside the body as a whole, and part of the traction wire is located in the fixation bolt. The length of the wire can be adjusted according to the position of the diseased tissue and then the fixation rod is pressed to one side. , the perforation in the fixing rod and the round hole in the national plug are dislocated to lock the traction wire, so that the traction wire is stuck between the fixing bolt and the fixing rod for fixation, thereby fixing the diseased tissue. The diseased tissue is then processed. If only the tissue needs to be ligated, only the traction rod and the traction wire can be used to ligate the tissue after entering the abdominal cavity through the endoscopic operation hole.

The traction and ligation device of the utility model can puncture the abdominal wall with a puncture needle and enter the abdominal cavity to perform ligation and traction on the target tissue to cooperate with the operation, so as to achieve the same effect as the use of endoscopic instruments, and avoid the need for inserting "trocar". Abdominal wall incision, which can reduce the number of abdominal incisions in patients during multi-port laparoscopy and leave less scars; while applying this device in single-port laparoscopy does not increase the number of abdominal scars in patients, and can play a similar role in increasing the number of abdominal incisions. The effect of operating the instrument is equivalent to the multi-hole operation, which makes the operation more convenient, thereby reducing the difficulty and risk of the operation. In addition, the traction rod combined with the traction wire can be used alone as an independent device, and can be used as a ligation device in laparoscopic surgery, which saves the steps of making a ligation coil during the operation and saves the operation time.
