Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of needle removers, and more specifically, to a novel needle remover. Background Art
[0002] A stapler is a device used in medicine to replace manual suturing. Its main working principle is to use titanium nails to separate or staple tissues, similar to a stapler. There are many types of staplers, and a series of precautions need to be taken during use. After suturing the internal tissues, the needle inside the device needs to be removed. However, in actual use, the needle inside the stapler device is not easy to remove. Due to its small nature, the general clamping device will loosen, which increases the difficulty of work for the user. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present utility model provide a new needle remover to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel needle remover, comprising a positioning block, a clamping and fixing block, a locking sleeve, a fixing tube, a clamping claw, a clamping bracket, and a suture outer tube, wherein a clamping and fixing block is fixedly installed on one side of the positioning block, a locking sleeve is embedded and installed on one side of the clamping and fixing block, a clamping bracket is fixedly installed on one side of the positioning block, a clamping claw is installed on one end of the clamping bracket, and a suture outer tube is sleeved on one end of the positioning block;
[0005] A fixing pipe is installed at one end of the locking sleeve.
[0006] As a further improvement of the technical solution of the utility model, the locking sleeve passes through the positioning block and the clamping and fixing block.
[0007] As a further improvement of the technical solution of the utility model, the fixed pipe sleeve is outside the two groups of clamping brackets to limit their positions.
[0008] As a further improvement of the technical solution of the utility model, tooth grooves are arranged on the inner side of the clamping jaws.
[0009] As a further improvement of the technical solution of the utility model, the clamping bracket is in a V-shape and open in a natural state.
[0010] As a further improvement of the technical solution of the utility model, a needle entry port is provided on the side of the outer tube of the suturing device.
[0011] As a further improvement of the technical solution of the utility model, a limiting groove is provided on the clamping and fixing block, and a limiting block fixed to the surface of the locking sleeve is arranged in the limiting groove.
[0012] Technical effects and advantages of the utility model:
[0013] The utility model improves the previous design by utilizing a movable fixing tube in combination with a clamping claw to clamp the needle on the stapler for removal, which greatly facilitates people's operation and improves the stability and convenience of clamping.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 A novel needle remover shown in the figure comprises a positioning block 1, a clamping and fixing block 2, a locking sleeve 3, a fixing tube 4, a clamping claw 5, a clamping bracket 6, and a suture outer tube 7. The clamping and fixing block 2 is fixedly installed on one side of the positioning block 1, and the locking sleeve 3 is embedded and installed on one side of the clamping and fixing block 2. The clamping bracket 6 is fixedly arranged on one side of the positioning block 1, and the clamping claw 5 is installed on one end of the clamping bracket 6. The suture outer tube 7 is sleeved on one end of the positioning block 1;
[0020] A fixing tube 4 is installed at one end of the locking sleeve 3 .
[0021] Further Figure 1 As shown, the locking sleeve 3 passes through the positioning block 1 and the clamping and fixing block 2 .
[0022] Further Figure 1 As shown, the fixing tube 4 is sleeved on the outside of the two groups of clamping brackets 6 to limit their positions.
[0023] Further Figure 1 As shown, the inner side of the clamping jaw 5 is provided with tooth grooves to increase the friction resistance of the clamping jaw, thereby clamping the needle.
[0024] Further Figure 1 As shown, the clamping bracket 6 is in a V-shape in a natural state and is open, so that the clamping bracket 6 is in an open state when not clamped, thereby releasing the clamped needle.
[0025] Further Figure 1 As shown, a needle entry port is provided on the side of the suture device outer tube 7 , so that the needle on the suture device can enter from the needle entry port and be clamped by the clamp 5 .
[0026] Further Figure 1 As shown, a limiting groove is provided on the clamping and fixing block 2, and a limiting block fixed to the surface of the locking sleeve 3 is arranged in the limiting groove.
[0027] Working principle of this utility model:
[0028] The utility model patent mainly designs a needle remover for a suture device. When the needle of the suture device enters the outer tube 7 of the suture device from the needle entrance, at this time, the entire device is aligned with the outer tube 7 of the suture device, and the positioning block 1 is stuck at the outer edge position. The positioning block 1 is held and the locking sleeve 3 is pushed inward. The locking sleeve 3 drives the fixing tube 4 to move forward, thereby squeezing the clamping bracket 6, so that the claws 5 on the two groups of clamping brackets 6 clamp the needle, and then the needle is taken out.
[0029] Secondly: In the drawings of the embodiments disclosed in the present utility model, only the structures related to the embodiments disclosed in the present utility model are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
