Description

Clip type automatic tissue suspension device

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a clip type automatic tissue suspension device.

Background

In laparoscopic minimally invasive surgery, other various tissues and organs overlapped on target tissues and organs in an abdominal cavity are often required to be separated and suspended, so that the surgical field of vision can be better exposed, and the target surgery can be clearly and safely performed. The traditional method comprises the following steps: 1. the patient is moved to change his posture (e.g., Trendelenburg position) to obtain a better surgical field, which is inconvenient and may cause more trauma to the patient; 2. by adding abdominal wall puncture pore channels (such as 5mm and 10mm puncture outfits), some special surgical instruments are placed, and hands are added to poke tissues, so that the purpose of exposing the surgical field is achieved, abdominal incisions are increased, wounds are increased, labor force of doctors is increased, and cost is increased; 3. according to the experience of doctors, one end of an operation suture is fixed on a tissue to be suspended, and the other end of the operation suture is led out of the abdominal wall to be drawn and fixed to realize suspension, which is a common 'soil method' for most surgeons at present, is simple and effective, but lacks standardization and a special suspension fixing device, and has great effect difference; 4. the method introduced by other patents, such as the commodity introduced and converted by the publication No. CN 105286931B, can effectively realize the tissue suspension of partial operation scenes under the conditions of not obviously increasing trauma and not increasing labor force, but because the operation principle is that the operation is carried out from the abdominal exterior to the abdominal interior, the precision is lacked, the tissue suspension can not be realized in most operation scenes, and in addition, the product has no abdominal wall minimally invasive incision suture function.

Therefore, a product with a brand new principle and a brand new operation mode of the utility model is urgently needed to be awaited, which is the same as the product with the publication number CN 105286931B, does not occupy a minimally invasive pore channel, does not occupy the hands of a doctor, and does not increase the trauma; meanwhile, the product function of the bulletin No. CN 105286931B is required to be fully compatible downwards, and safe, accurate, effective, automatic and efficient suspension is required to be realized for important pipelines, dangerous areas and other tissues in the abdominal cavity; besides tissue suspension, the tissue suspension device also has the function of suturing an abdominal wall minimally invasive incision. The utility model perfectly realizes the functions due to the different operation principles and the specially designed thread grabber, realizes the efficient and automatic clipping of the tissue to be suspended by adapting to the ligature lock clamp or the pug clamp which is conventionally used in the minimally invasive surgery, and obtains more accurate suspension position and suspension angle from the abdominal cavity to the outside of the abdominal cavity, thereby achieving more satisfactory surgery effect and meeting the comprehensive requirements of clinical minimally invasive surgery in various aspects.

Contents of utility model

The utility model aims to solve the technical problems in the prior art and provides a clip type automatic tissue suspension device for automatically, efficiently, safely and accurately suspending tissues and minimally-invasively suturing abdominal wall incisions.

In order to achieve the purpose, the utility model adopts the following technical scheme:

According to the utility model, the wire grabber has an active wire grabbing function, so that the abdominal wall can be punctured, cotton wires of the suspender can be grabbed actively, and the suspender is assisted to realize a tissue suspension function; meanwhile, the suture device can be used for accurately suturing small incisions on the abdominal wall, such as a 10mm or 12.5mm puncture outfit commonly used in laparoscopic minimally invasive surgery, and small incisions left after the abdominal wall is punctured are most suitable for realizing effective suture of the small incisions by using the suture grasping device (see fig. 13 in detail). Compared with the single function of other patents (such as publication number CN 111956283A, CN 109907784A, CN 105286931B), the utility model realizes two basic functions: intra-abdominal tissue suspension and abdominal wall suturing. The operation scenes needing to use the tissue suspender are laparoscopic minimally invasive operations, and small abdominal wall incisions need to be sutured, so the utility model completely conforms to the requirements of the minimally invasive operation scenes, and one set of instruments meets the operation requirements to the maximum extent.

3. Compared with other suspenders (such as the publication No. CN 111956283A, CN 109907784A, CN 105286931B), although the purpose of realizing effective suspension of tissues is consistent, the realization principle and the operation process are completely different, other patents establish an abdominal wall suspension point, and use an opening puncture needle to puncture the abdominal wall at the point to lead to target tissues, and realize tissue suspension after releasing the suspenders, which is operated from outside to inside, the biggest defect is that: firstly, the abdominal wall puncture suspension point which is established in advance is often not the most effective point for realizing tissue suspension; secondly, the important tissues in the abdominal cavity and the tissues beside the important pipelines, such as the tissues beside the hepatic portal part, the great vessels in the abdominal cavity and the liver tissues, are suspended, the puncture is lack of accuracy, the tissues are easy to be accidentally injured, and even a part of application scenes can not be realized. In the utility model, the clamping type suspender is firstly sent to the suspension-simulated tissue in the abdomen by the ligature lock clamp or the haba dog clamp, the tissue is automatically clamped and buckled, the reverse operation process is realized, the tissue is accurately suspended from the inside of the abdomen to the outside of the abdomen, then the suspension wire is pulled in the abdominal cavity, the angles are compared and adjusted to well adjust the angle and the direction of the pulling suspension, the optimal puncture point is determined on the abdominal wall after the optimal direction is determined, then the suture grabber is punctured by the optimal puncture point, the cotton thread is grabbed out, and the most effective and accurate tissue suspension is realized, as shown in figure 12. Therefore, the utility model is most suitable for suspending tissues in important ducts, dangerous areas and the like in the abdominal cavity. Compared with other patents, the utility model has the advantages of more automation, high efficiency, more accuracy, more safety and wider application scenes, and can be downwardly compatible with the functions of the patent products, but cannot be upwardly compatible with the functions of the utility model.

4. Compared with PVC or plastic suspension wires of other patents, the suspension cotton wire is softer and has no edges and corners, has no abrasion and cutting damage to tissues and organs contacted with the periphery, and has more friendly contact protection, safety and no damage.

5. The utility model is disposable, and does not need to be disinfected repeatedly; when in use, the puncture outfit does not need to occupy other puncture outfit pore canals and does not conflict with other instruments; the hanger has small needle passage through the abdominal wall, can self-heal, does not need to be sutured, and has ultra-minimally invasive effect.

6. After the suspension device is used, the wire fixing device can effectively maintain the tissue traction suspension effect of the suspension device, improve the safety and efficiency of the operation, avoid the need of additionally increasing an operation doctor and save labor force.
