Description

Technical Field

[0001] The utility model relates to a lip retractor for suturing, belonging to the technical field of retractors. Background Art

[0002] When the lips are injured and cracked, it not only affects the appearance, but also has a significant impact on oral function. This kind of wound needs to be sutured in time to ensure wound healing and restore function. Because the oral mucosa is slippery, the conventional treatment method is that a doctor holds a large friction object such as gauze, pulls open the lip flap, exposes the wound on the inside of the lip flap, and then another medical staff performs the suture operation. However, this method has some inconveniences. First, since it requires the cooperation of multiple people, there may be poor communication or uncoordinated operation during the treatment process, which may affect the effect of the treatment. Secondly, this method requires more manpower input, especially in areas with scarce medical resources, which may cause waste of resources. Moreover, during the suturing process, medical staff need to concentrate, and the hand operation is cumbersome, which is prone to mistakes or delays in treatment time. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model inserts the first and second pull ropes of the pull rope from the second tube part of the telescopic bracket, and respectively passes through the port of the moving tube and the port of the first tube part to be connected with the lip clip. The distance between the two lip clips after being pulled together can be changed by sliding the moving tube through a limiting mechanism, so as to meet the different lengths of wounds in different parts and different tearing lengths. Then, the lip clips are clamped on both sides of the wound, and then the pull rope is pulled to move the lip clips toward the two ends of the telescopic bracket to achieve the effect of tearing the wound, so that the wound on the inner side of the lip is fully exposed, which is convenient for subsequent suturing. Then, the fixing clamp is clamped next to the guardrail of the operating table to fix the pull rope, and then the lip is sutured.

[0013] 2. The limiting mechanism of the utility model controls the extension or retraction position of the moving tube by sliding the block forward and backward in the first slide groove, and then rotates the moving tube so that the block is stuck in the slot to be fixed, so that the moving tube will not move when the pull rope is pulled.

[0014] 3. The one-way pulling mechanism of the utility model can prevent the pull cord from flowing back while pulling the pull cord outward when the wound needs to be further opened during the suturing process. When the pull cord is pulled outward, the moving direction of the pull cord is consistent with the tilt direction of the card, which will not hinder the movement of the pull cord. When the pull cord is pulled back by the reaction force generated by the wound, the end of the card contacts the pull cord and generates friction to prevent the pull cord from flowing back. Then the friction block at the lower end of the connecting rod contacts the pull cord due to the action of the spring, further strengthening the fixing effect. When the operation is completed and the pull cord needs to be reset, the connecting ring is pushed toward the card, and the connecting ring drives the sliding block to move in the second slide groove. The lower end of the sliding block drives the push ring to move toward the card. The push ring expands the card so that it does not contact the pull cord. Then the rod cap is pulled up to move the friction block upward, and then the pull cord can be pulled freely. BRIEF DESCRIPTION OF THE DRAWINGS
