Description

Technical Field

[0001] This utility model relates to a multifunctional needle holder for thoracic surgery, belonging to the technical field of needle holders. Background Technology

[0002] Surgery is the science that studies the occurrence, development, and clinical manifestations of surgical diseases, as well as their diagnosis, prevention, and treatment. It is a specialized department that primarily uses surgical resection and repair to treat diseases. With the application of microsurgical techniques, surgery has made significant progress, and there are many types of surgical procedures, including thoracic surgery.

[0003] Chinese Patent Publication No. (CN 208301686 U) discloses a needle holder for gripping suture needles. It includes a first clamp body and a second clamp body connected to the first clamp body. The first clamp body includes a first clamp head, a first clamp handle, and a first clamp rod connecting the first clamp head and the first clamp handle. The first clamp head is perpendicular to the first clamp rod, which is a hollow rod with an opening at one end connected to the first clamp head. The second clamp body slides through the first clamp rod to the opening and engages with the first clamp head to grip the suture needle. This invention enables a more secure gripping of the suture needle, preventing it from easily slipping out.

[0004] The aforementioned device relies solely on the doctor's hand grip strength to hold the needle. However, surgical procedures are usually lengthy, and when the doctor applies significant grip strength for an extended period, it may lead to a loss of strength in the doctor's hand, causing hand tremors and reducing the stability of the doctor's needle holding, which in turn affects the wound suturing process.

[0005] Therefore, a multifunctional needle holder for thoracic surgery is proposed. Utility Model Content

[0006] In view of this, the present invention provides a multifunctional needle holder for thoracic surgery to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A multifunctional needle holder for thoracic surgery includes a housing and two needle clamping heads. Both needle clamping heads are located at the top of the housing, and each of the two needle clamping heads has a needle clamping groove on its inner side. An assisting mechanism is provided in the inner cavity of the housing. The assisting mechanism includes a sliding rod, which is fixedly installed in the inner cavity of the housing. Sliding blocks are slidably connected to the left and right sides of the surface of the sliding rod. Hard springs are fixedly installed on the outer sides of the two sliding blocks. The other ends of the two hard springs are fixedly connected to the left and right sides of the inner cavity of the housing. Clamping clamps are fixedly installed on the top of the two sliding blocks, and gripping rods are fixedly installed on the bottom of the two sliding blocks.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6 As shown, this utility model embodiment provides a multifunctional needle holder for thoracic surgery, including a housing 1 and two needle clamping heads 3. Both needle clamping heads 3 are located at the top of the housing 1, and each needle clamping head 3 has a needle clamping groove 4 on its inner side. An assisting mechanism 2 is provided in the inner cavity of the housing 1. The assisting mechanism 2 includes a slide rod 201, which is fixedly installed in the inner cavity of the housing 1. Sliding blocks 202 are slidably connected to the left and right sides of the surface of the slide rod 201. Hard springs 203 are fixedly installed on the outer sides of both sliding blocks 202, and the other ends of the two hard springs 203 are fixedly connected to the left and right sides of the inner cavity of the housing 1. The top of each of the two sliders 202 is fixedly equipped with a clamping plier 204, and the bottom of each of the two sliders 202 is fixedly equipped with a gripping rod 205. The surface of each of the two gripping rods 205 is provided with a finger slot 206. The front and rear sides of the inner cavity of the housing 1 are provided with a sliding groove 207. The front and rear sides of the two sliders 202 are slidably connected to the inner cavity of the two sliding grooves 207. The bottom of the housing 1 is provided with a movable groove 208. The two gripping rods 205 pass through the inner cavity of the movable groove 208 and extend to the bottom of the housing 1. The top of the housing 1 is provided with a moving groove 209. The two clamping pliers 204 pass through the inner cavity of the moving groove 209 and extend to the top of the housing 1.

[0031] By setting up the assist mechanism 2, the tension of the rigid spring 203 causes the slider 202 to drive the clamping forceps 204 and the gripping rod 205 to move inward. The auxiliary force applied by the rigid spring 203 can reduce the force applied by the doctor's hand, preventing the doctor from applying force for a long time, which could cause the hand to shake and affect the stability of holding the needle. By setting up the slide groove 207, the movement of the slider 202 can be limited to prevent the slider 202 from deviating during movement, which would affect the clamping of the needle. By setting up the movable groove 208, the movement of the gripping rod 205 can be limited to prevent the gripping rod 205 from deviating during movement, which would affect the clamping stability of the needle. By setting up the movable groove 209, the movement of the clamping forceps 204 can be limited to prevent the clamping forceps 204 from changing direction during movement, which would affect the clamping effect of the needle.

[0032] Example 2

[0033] like Figure 1 and Figure 5 As shown, in one embodiment, the front sides of the two clamping clamps 204 are threaded with mounting bolts 7, and the rear sides of the two mounting bolts 7 are threaded to the inner surfaces of the two needle clamps 3. The outer sides of the two needle clamps 3 are provided with a prying groove 5, and the prying groove 5 is toothed. The inner sides of the two clamping clamps 204 are fixedly installed with hemostatic clamps 6, and the two hemostatic clamps 6 are the same size. The front and rear sides of the housing 1 are fixedly installed with lighting fixtures 8, and the inner cavities of the two lighting fixtures 8 are provided with lighting bulbs.

[0034] The mounting bolt 7 allows for easy disassembly of the needle clamp 3, facilitating its replacement after prolonged wear. The opening groove 5 allows for easy outward opening of the wound, enabling doctors to better observe its condition. The hemostatic clamp 6 provides hemostasis, enhancing the overall functionality of the device. The lighting fixture 8 illuminates the wound area, improving the ease of suturing for doctors.

[0035] In operation, the doctor inserts their finger into the inner cavity of the finger slot 206 and pulls it outward. At this time, the gripping rod 205 simultaneously moves the slider 202 outward. The rigid spring 203 deforms due to the compression of the slider 202. The clamping forceps 204 moves the needle clamping head 3 outward in sync with the slider 202. The needle body is then placed inside the needle clamping head 3. The doctor's finger then moves the gripping rod 205 and the slider 202 inward. At this time, the outward force disappears, and the rigid spring 203 deforms again due to its own tension, simultaneously pushing the slider 202 to move the clamping forceps 204 and the needle clamping head 3 inward. The needle body is then engaged in the inner cavity of the needle clamping groove 4, thus completing the clamping of the needle body.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
