Description
Technical Field
The invention relates to a tissue stretching and closing instrument for wound repair.
Background
Soft tissue defects of the skin are a common surgical problem in the clinic. For the common skin soft tissue defects with low tension and small area of local wound skin, a direct suture method is usually adopted clinically; for skin defects with large local defects or large wound skin tension, the skin defects are not directly sutured clinically, and other methods are adopted to repair and reconstruct the wound.
The skin stretching operation is to draw normal skins at two sides of a wound edge to the center through external force, and generate 'extra' skin through linear load circulation by utilizing the viscoelasticity and mechanical extensibility of the skin, so that the wound is closed, the wound surface is quickly closed, the complications are few, all skin organs and corresponding functions are reserved, and the operation is simple. The theoretical basis is that the normal skin proposed by Gibson has viscoelastic property, namely the biological characteristics of crawling and stress relaxation, and the skin can crawl, expand and stretch under the action of external continuous traction, compression and the like.
The existing skin stretching device only adopts superficial layer or full layer stretching, the strength is not accurate enough, and the device is positioned outside the skin, the action and the bed rest of a patient are disturbed, and the nursing and dressing change are relatively troublesome.

Aiming at the defects of the prior art, the invention designs a tissue stretching and closing instrument for wound repair. The device can guide the traction closing device into different depth layers of tissues, and according to the anatomical layers of human tissues, the traction closing device can be used for traction closing layer by layer, so that the physiological process of wound surface repair is met, and the comfort degree of a patient and the wound surface repair speed are greatly improved.
The aim of the method is to select the most suitable mode to accelerate the physiological healing and reconstruction of wound tissues, pursue the minimum injury, the minimum pain and the fastest effect.
The specific invention content is as follows:
a tissue stretching and closing instrument for wound surface repair comprises a stretching and closing device and an introduction device;
the traction closing device comprises a titanium wire and an resistance increasing titanium pipe;
the guiding device comprises a handle and a guide pin; the guide pin comprises a guide pin A and a guide pin B;
the guide pin A is matched with the resistance-increasing titanium tube for use, and comprises a needle rod and a needle head part, wherein the needle rod can be sleeved into an inner cavity of the resistance-increasing titanium tube; when the needle rod is sleeved in the inner cavity of the resistance-increasing titanium tube, the needle head part at one end of the needle rod blocks one end of the resistance-increasing titanium tube and cannot be sleeved in the inner cavity of the resistance-increasing titanium tube;
the one end of keeping away from the syringe needle of guide pin A with guide pin B all can dismantle fixed connection with the handle.
It should be noted that when the guide pin A is sleeved on the resistance-increasing titanium tube, a gap is formed between the needle rod and the inner cavity of the titanium tube, which is beneficial for the titanium wire and the guide pin A to pass through.
The use method of the tissue stretching and closing instrument comprises the following steps:
the method comprises the following steps: fixing a titanium wire on the guide pin A, and sleeving the guide pin A and the resistance-increasing titanium pipe together; the guide pin A is detachably fixed on the handle; making a small incision on the skin, holding a handle by hand, guiding a traction and expansion closing device to a required depth by a guide pin A, selecting a position penetrating out of the skin according to the selected length of the resistance-increasing titanium tube, penetrating out of the skin, separating the guide pin from the handle, embedding the resistance-increasing titanium tube into a tissue, leading a titanium wire out of an outlet, and separating the titanium wire from the guide pin A; completing the implantation of a titanium tube at one side of the wound surface;
step two: then selecting a guide pin B, installing a titanium wire in the guide pin B, detachably fixing the guide pin B on a handle, re-entering a selection layer from a through-out port, penetrating through two sides of a wound, penetrating out from the opposite side skin, separating the guide pin B from the handle, leading out the titanium wire, and separating the guide pin B from the titanium wire;
step three: fixing the titanium wire penetrating out of the skin on the guide pin A again, and sleeving the guide pin A and the resistance-increasing titanium pipe together; detachably fixing the guide pin A to the handle, penetrating the guide pin A into the handle to the required depth from the penetrating and discharging port in the second step, selecting the position where the guide pin A penetrates out of the skin according to the selected length of the resistance-increasing titanium tube, penetrating out of the skin, separating the guide pin A from the handle, burying the resistance-increasing titanium tube into the tissue, leading out the titanium wire from the discharging port, and separating the titanium wire from the guide pin A; completing the implantation of the titanium tube on the other side of the wound surface;

When the external thread of the guide pin is screwed into the nut, the titanium wire fixing groove of the guide pin can be aligned with the titanium wire placing groove; the titanium wire twines in the titanium wire fixed slot, and outside its one end was derived the nut from the titanium wire standing groove, did not receive the separation that increases the titanium pipe.
Furthermore, a nut bayonet is arranged at one end of the handle connected with the guide pin, and the nut can be clamped on the handle, so that the nut can be detachably fixed on the handle. The nut can rotate relative to the external thread part of the guide pin without disengaging under the fixation of the nut bayonet on the handle, and the guide pin A or the guide pin B can be fixed through the rotation of the nut.
Furthermore, a guide pin stabilizing device which can be jointed with the resistance-increasing titanium tube and then is attached to the wall of the inner cavity of the resistance-increasing titanium tube is arranged between the needle head part of the guide pin A and the needle rod, and the guide pin stabilizing device is preferably a guide pin stabilizing ring surrounding the axis of the needle rod, so that the needle rod is prevented from sliding or vibrating relative to the inner cavity of the titanium tube, and stable operation is facilitated;
still further, the terminal surface of the nut that keeps away from the one end of handle set up the titanium pipe storage tank that can hold increase and hinder the titanium pipe, the internal diameter of titanium pipe storage tank is preferred to be slightly greater than the titanium pipe external diameter, can prevent the slip aversion of titanium pipe, is favorable to stabilizing the operation.
Further, the inner walls at the two ends of the resistance increasing titanium pipe comprise thickened areas surrounding the axis of the resistance increasing titanium pipe. The radial cross section of the thickening area along the resistance increasing titanium pipe is preferably arc-shaped, so that the movement of the titanium wire in the stress application process is facilitated, the resistance is reduced, and the titanium wire sliding is facilitated.
Furthermore, the end parts of the titanium wires are provided with lock catches, the titanium wires at two ends can be fixed and exposed outside the body, and the traction force of the titanium wires can be adjusted through the lock catches later.
