Description

Technical Field

[0001] The utility model relates to the technical field of suturing instruments, in particular to a surgical suturing device for suturing threads. Background Art

[0002] The more common surgical operations include debridement and suturing. Suturing is the process of matching or reconstructing the channels of tissues and organs that have been cut or broken by trauma, so that the tissues or organs can restore their functions. It is a basic condition to ensure good healing of tissues or organs. The commonly used instruments for suturing include suture needles, suture threads and other suture instruments.

[0003] However, during the use of existing surgical staplers for sutures, the needle tip of the suture needle will constantly come into contact with the skin and surgical forceps, making the needle tip of the suture needle more susceptible to wear. Since the suture needle and the stapler are usually fixed on the stapler and are difficult to separate, it is troublesome and time-consuming to replace the suture needle with the stapler. In addition, when the stapler drives the suture needle to puncture tissues or organs, the needle tip that penetrates the tissues or organs will be directly exposed to the outside and can easily prick the surgeon's fingers, resulting in lower safety of the stapler when in use and increasing the risk of infectious occupational exposure to the surgeon. Utility Model Content

[0004] The purpose of the utility model is to provide a surgical stapler for sutures to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surgical stapler for sutures, comprising a middle handle, a screw hole is provided at the top end of the middle handle, an externally threaded barrel is movably threaded inside the screw hole, a suture needle is fixedly connected to the top end of the externally threaded barrel, a pressure rod is provided at the top of the suture needle, a rotary spring is provided at the bottom of the pressure rod, a cavity is provided inside the middle handle, a round ball is movably embedded inside the cavity, a transparent cover is embedded in the outer wall of the middle handle, a tail handle is fixedly connected to the bottom end of the middle handle, and a plurality of corrugated grooves are provided on the outer wall of the tail handle.

[0006] Preferably, the suture needle is movably connected to the middle handle via an external threaded tube.

[0007] Preferably, a groove is formed at the top of the caudal stalk.

[0008] Preferably, a clamping rod penetrates the bottom end of the pressure rod, and the clamping rod is movably connected with the groove.

[0009] Preferably, the rotary spring is movably sleeved on both ends of the clamping rod, and the pressure rod is movably connected to the tail handle through the clamping rod.

[0010] Preferably, the top end of the pressure rod is movably connected to the top end of the suturing needle.

[0011] Preferably, the transparent cover is connected to the cavity movable cover.

[0012] Preferably, a threading hole is provided at the bottom of the suture needle.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The surgical stapler for sutures has an external threaded barrel, a tail handle, a screw hole and a corrugated groove, so that the bottom end of the suture needle can be connected and fixed to the stapler through a thread, so that the suture needle can be replaced by twisting it, which reduces the difficulty of separating the suture needle from the stapler, thereby saving the time required for replacing the suture needle with the stapler.

[0015] 2. The surgical stapler for sutures uses the ball and the cavity so that when the stapler pushes the suture needle to puncture tissues or organs, the position of the ball in the cavity can be observed through the transparent cover, so as to judge the position of the suture needle, which is convenient for the surgeon to predict the position of the needle tip of the suture needle. In combination with the pressure rod and the rotary spring, the needle tip of the suture needle can be pressed by the end of the pressure rod when it passes through the tissue or organ, thereby reducing the probability of the needle tip of the suture needle piercing the surgeon's finger, improving the safety of the stapler when in use, and reducing the risk of infectious occupational exposure of the surgeon.

[0024] like Figures 1 to 4As shown, the surgical stapler for suture thread of this embodiment comprises a middle handle 3, the material of the middle handle 3 is the same as that of the suture needle 1, but the portion below the middle handle 3 does not continue to penetrate the tissue after the threading hole 10 of the suture needle 1 penetrates the tissue, so that the puncture site of the stapler is the suture needle 1, and at the same time, the cavity 4 at the middle handle 3 and the round ball 5 in the cavity 4 can roll, which is convenient for the surgeon to observe the puncture situation of the suture needle 1, and the top of the middle handle 3 is provided with a screw hole 11, and the inner diameter of the screw hole 11 is the same as the outer diameter of the external threaded barrel 2. The external threaded barrel 2 is adapted so that it can be well connected with the screw hole 11. The internal movable thread of the screw hole 11 is connected with the external threaded barrel 2. The external threaded barrel 2 and the suture needle 1 are an integrated structure. The top of the external threaded barrel 2 is fixedly connected with the suture needle 1. The top of the suture needle 1 is provided with a pressure rod 9. The pressure rod 9 is a straight rod, so that the pressure rod 9 can be pressed on the needle head of the suture needle 1, thereby facilitating the covering of the needle head of the suture needle 1 that penetrates the tissue, and preventing the needle head of the suture needle 1 from piercing the fingers of the surgeon. The bottom of the pressure rod 9 is provided with a rotation spring. 13. When the return spring 13 is in the initial state, the top end of the pressure rod 9 can keep pressing on the needle head of the suture needle 1. A cavity 4 is opened inside the middle handle 3. The inner diameter of the cavity 4 is matched with the outer diameter of the round ball 5, so that the round ball 5 in the cavity 4 can only slide back and forth along the cavity 4, so that the moving track of the round ball 5 is the length of the cavity 4. The round ball 5 is embedded in the cavity 4. The round ball 5 is a solid structure and bright yellow in color. A transparent cover 12 is embedded in the outer wall of the middle handle 3. The transparent cover 12 is made of a transparent resin material. The surface is smooth and not easy to adhere to body fluids, so that the transparent cover 12 can maintain a light-transmitting state, which is conducive to seeing the position of the round bead 5 in the cavity 4. The bottom end of the middle handle 3 is fixedly connected to the tail handle 6, and the tail handle 6 and the middle handle 3 are combined into a semicircular structure, which makes it easier for the suturer to push the suture needle 1 to puncture tissues or organs. The outer wall of the tail handle 6 is provided with a plurality of corrugated grooves 7, which can increase the friction of the tail handle 6 when it is clamped by surgical forceps, making it easier for the surgeon to clamp the tail handle 6, which is convenient for the surgeon to use the surgical stapler.

[0025] Specifically, the suture needle 1 is movably connected to the middle handle 3 through the external threaded tube 2. The suture needle 1 can be connected to the screw hole 11 at the top of the middle handle 3 through the external threaded tube 2, so that the suture needle 1 that is severely worn can be replaced in time, reducing the difficulty of replacing the suture needle 1.

[0026] Furthermore, a groove 14 is provided at the top of the tail handle 6, and the groove 14 allows the bottom end of the pressure rod 9 to move at the top of the tail handle 6, thereby separating the top of the pressure rod 9 from the top needle head of the suture needle 1, reducing the interference of the pressure rod 9 on the suture needle 1 when puncturing the skin.

[0027] Furthermore, a clamping rod 8 passes through the bottom end of the pressure rod 9, and the clamping rod 8 is movably connected to the groove 14. The clamping rod 8 can limit the bottom end of the pressure rod 9 in the groove 14 at the top end of the tail handle 6, so that the pressure rod 9 is more stable when connected to the top end of the tail handle 6.

[0028] Furthermore, the rotary spring 13 is movably sleeved on both ends of the clamping rod 8, and the pressure rod 9 is movably connected to the tail handle 6 through the clamping rod 8. The rotary spring 13 can drive the top of the pressure rod 9 to be pressed against the top of the suture needle 1 in time, so that when the suture needle 1 penetrates the tissue or organ, the needle tip is not easy to pierce the surgeon's fingers, thereby reducing the probability of the surgeon's fingers being pierced and reducing the probability of the surgeon's occupational exposure to infections.

[0029] Furthermore, the top end of the pressure rod 9 is movably connected to the top end of the suture needle 1. Under the action of the rotary spring 13, the pressure rod 9 can maintain a pressed state with the suture needle 1. At the same time, when it is pushed by an external force, it can be temporarily separated from the needle head at the top end of the suture needle 1 to reduce the interference with the puncture of the tissue or organ by the needle head of the suture needle 1.

[0030] Furthermore, the transparent cover 12 is connected to the movable cover of the cavity 4, so that the surgeon can observe the position of the round ball 5 in the cavity 4 through the transparent cover 12, which can help the surgeon predict the trajectory of the needle tip of the suture needle 1 passing through the tissue and reduce the probability of the suture needle 1 piercing the surgeon's finger.

[0031] Furthermore, a threading hole 10 is provided at the bottom of the suture needle 1, and the threading hole 10 is located at the bottom of the suture needle 1, so that the subsequent middle handle 3 and other structures of the suture needle 1 do not need to pass through the tissue or organ in its entirety, thereby shortening the suturing time of the suture needle 1 and making the suture device more convenient and quick to use.

[0032] The method of using the present embodiment is as follows: when using the present surgical stapler, the suture needle 1 to be used needs to be firstly screwed into the screw hole 11 at the top end of the middle handle 3 through the externally threaded tube 2, so that the suture needle 1 is combined and fixed with the middle handle 3. At the same time, after the suture needle 1 is fixed, the needle head at the top of the suture needle 1 will fit with the top end of the pressure rod 9, so that the needle head of the suture needle 1 is protected. Then, when using the suture needle 1 to puncture the tissue, the pressure rod 9 needs to be pushed away from the top of the suture needle 1. At this time, the clamping rod 8 at the bottom end of the pressure rod 9 and the return spring 13 on the clamping rod 8 will rotate along the groove 14 at the top end of the tail handle 6, so that the return spring 13 is deformed. Then, the suture needle 1 separated from the pressure rod 9 can be inserted into the tissue, and then the round ball in the cavity 4 can be observed through the transparent cover 12 at the middle handle 3. 5, when the round ball 5 in the cavity 4 slides from one end of the cavity 4 to the other end, it means that the needle head of the suture needle 1 is about to pass through the inner side of the tissue. At this time, the pressure rod 9 is released, so that the pressure rod 9 that has passed through is rotated and restored to its initial state under the force generated by the deformation of the rotary spring 13, and is pressed on the needle head of the suture needle 1 that is about to pass through. When the needle head of the suture needle 1 passes through, it will fit with the top of the pressure rod 9. At this time, the needle head of the suture needle 1 is covered by the pressure rod 9, so that the needle head is not easy to pierce the fingers of the surgeon. At the same time, when it is necessary to replace the severely worn suture needle 1, it is only necessary to clamp the corrugated groove 7 on the tail handle 6, and then twist the suture needle 1 to separate the external threaded barrel 2 at the bottom end of the suture needle 1 from the screw hole 11 at the top end of the middle handle 3, and finally replace it with a new suture needle 1.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
