Description

Tissue Graspers to Measure Tissue Tension

technical field

The utility model relates to a medical device, in particular to a tissue grasping forceps capable of measuring tissue tension.

Background technique

When the human tissue is torn (such as the rotator cuff tissue), the torn tissue needs to be grasped during the operation, and then the tissue is pulled, reset, sutured, fixed, etc., so that the human tissue can heal itself. Fresh tissue tears are easily pulled back to the original anatomical site for suturing and fixation. Old tears will cause excessive tissue tension due to tissue degeneration and retraction. The greater the tension, the harder it is to pull the tissue back to the original Anatomical site (if the tissue with high tension is forcibly fixed on the original anatomical site, it will cause human mechanical disorder and affect the healing of the tissue), so an appropriate tension value should be taken when suturing and fixing the tissue. Too little tension is not appropriate. Moreover, if there is no large amount of specific clinical data, it is not conducive to the research of medical science. At present, doctors judge the appropriate tension value for suturing and fixing according to their own experience. At present, there is no tissue grasping forceps for measuring tissue tension on the market.

Utility model content

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a grasping forceps capable of measuring tissue tension, which satisfies the doctor's need to accurately know when the tissue needs to be pulled according to the degree and time of tissue tearing, and the required pulling force for tearing The need for optimal results in fissured tissue recovery.

The technical solution adopted by the utility model to solve its technical problems: the tissue grasping forceps that can measure tissue tension include a forceps body, the forceps body includes a support block, a fixed handle fixed on the support block, and a handle connected to the fixed handle in rotation. Movable handle, the end of the support block is fixed with a clamp rod, the end of the clamp rod is installed with a clamp, the movable handle is connected with a pull bar that controls the opening or clamping of the clamp, and the support block is equipped with a handle that can reset the movable handle. The return spring of the fixed handle is fixed with the first clamp, the inner side of the movable handle is fixed with the second clamp, the inner surface of the first clamp and the outer surface of the second clamp are fixed with sawtooth hooks, the first clamp and the second clamp The shape and position are matched, and the outer end of the support block is provided with a miniature tension sensor. One end of the miniature tension sensor is fixed at the outer end of the support block, and the other end is fixed with a pull ring. The miniature tension sensor and the pincer rod are on the same axis. The miniature tension sensor selected here is an existing product on the market, and the product of Bengbu Sensor System Engineering Co., Ltd., the product model is JLBM, or a component with the same function can also be selected; the function of the pull ring here is that it can be used conveniently Fingers hook the pull ring to pull the entire grasper body, so that the pulling force of the grasper for tearing tissue can be accurately measured, with accurate precision, high efficiency, and small size; the miniature tension sensor and the forceps rod are on the same axis The above function is to increase the pulling accuracy and avoid the angle between the micro tension sensor and the pliers rod when pulling, which will make the pulling force inaccurate.

Further improvement, the side of the support block is provided with a long plane, on which a slide rail along the "X" direction is fixed, a ball slider is slidably connected to the slide rail, and a long rod is fixed on the outer end of the ball slide . Here, the functions of the long plane, the slide rail, the ball slider, and the long rod are to hold the long rod with one hand to maintain the balance of the entire gripper, and pull the pull ring with the other hand, so as to keep the gripper in a relatively stable position. Pull the tissue in the case of deviation, reduce the patient's discomfort caused by the deviation and pulling of the grasper; here, the friction between the ball slider and the slide rail is very small and can be ignored. If there is friction, the grasper can also be used The value obtained by stretching before the torn tissue is not clamped, and the value obtained by pulling the torn tissue after the grasper clamps the torn tissue, the difference between the two can obtain the accurate value.

As a further improvement, the long rod is covered with a non-slip rubber sleeve. The role of the anti-slip rubber sleeve here is to increase the friction between the hand and the long rod, thereby preventing the grasping forceps from sliding or falling, affecting the operation and reducing the discomfort of the patient.

For further improvement, a display screen capable of displaying the tension value of the miniature tension sensor is installed on the long pole. Here the display screen can display the tension value of the miniature tension sensor, so that it can be conveniently observed and recorded vertically.

The beneficial effects of the utility model are: the structure design of the utility model is ingenious and reasonable, and by using the way of installing a miniature tension sensor on the grasping forceps, the pulling force of the grasping forceps pulling the torn tissue can be accurately known, thereby recording the value, and according to the patient's To judge the recovery of the stretching value for the torn tissue, if the recovery is good, the value can be used, and if the recovery is not good, then the next case can be used to accurately stretch the value, and a large number of clinical cases can be used to obtain accurate The stretching value corresponds to the tear size and atrophy of different tissues, and then generates a numerical standard to perform related operations related to the recovery of the torn tissue. It is also beneficial to medical science to achieve the effect that any doctor can perform this type of operation according to relevant parameters. The research is worthy of popularization and application.
