Technical Field
[0001] This utility model relates to the field of surgical needle holders, and more specifically, to a needle holder for general surgery. Background Technology
[0002] In general surgery, the needle holder is an indispensable and important instrument.
[0003] Most existing surgical needle holders are scissor-like, clamping the needle at the end, which has certain drawbacks. A narrow gap exists at the junction of the middle section of this type of holder, allowing blood and tissue fluid to easily remain during surgery, creating an environment conducive to the growth of bacteria and other microorganisms. Furthermore, the narrow gap makes thorough sterilization difficult using conventional methods, thus creating a risk of infection. In addition, the contact point between the head and the surgical needle in traditional needle holders is usually fixed and cannot be replaced. If sterilization is incomplete, bacterial residue can easily lead to cross-infection in subsequent surgeries, seriously affecting postoperative recovery and even threatening the patient's life. Therefore, inventing a surgical needle holder for general surgery to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a needle holder for general surgery, which aims to improve the gaps at the junction of the needle holder. During the operation, blood, tissue fluid and other substances remain in the gaps and are difficult to disinfect completely. At the same time, the contact part between the head of the needle holder and the surgical needle is usually fixed and difficult to replace. If disinfection is not thorough, cross-infection can easily occur in subsequent operations.
[0005] This utility model is implemented as follows: a needle holder for general surgery, comprising...
[0006] The needle holder body includes a needle holding handle, and the two ends of the needle holding handle are limited and locked with replacement clamp heads;

[0008] The replaceable clamping head includes a clamping head that clamps the surgical needle. A connecting cylinder is fixedly connected to the outer end of the clamping head, and the connecting cylinder is limitedly connected to the end of the clamping arm.
[0009] In a preferred embodiment of this utility model, the arc-shaped back plate is C-shaped, and both ends of the arc-shaped back plate are fixedly connected to one end of the clamping arm, and the clamping arm is elastically connected to the arc-shaped back plate.
[0010] In a preferred embodiment of this utility model, a tapered head is fixedly connected to one end of the clamping arm away from the arc-shaped back plate, and a connecting rod is fixedly connected to the other end of the tapered head.
[0011] In a preferred embodiment of this utility model, the cross-sections of the arc-shaped back plate and the clamping arm are both rectangular, and the top view of the clamping arm is an isosceles trapezoid.
[0012] In a preferred embodiment of this utility model, the end of the tapered head near the clamping arm is rectangular, the end of the tapered head connected to the connecting rod is circular, the two ends of the tapered head are smoothly transitioned, and the connecting rod is a smooth cylindrical shape.
[0013] In a preferred embodiment of this utility model, the connecting sleeve is sleeved on the outside of the connecting rod, and a positioning bolt is threaded through the top of the connecting sleeve, the positioning bolt being limited and abutting against the outer wall of the connecting rod.
[0014] In a preferred embodiment of this utility model, an extension cylinder is fixedly connected to the outside of the connecting cylinder, the threaded part of the positioning bolt is located inside the extension cylinder, and a screwing disc is provided on the top of the positioning bolt, with the screwing disc located outside the extension cylinder.
[0015] In a preferred embodiment of this utility model, an extension head is fixedly connected to one end of the clamping head, and an anti-slip plate is fixedly connected to the bottom of the clamping head and the extension head.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Please see Figure 1 and Figure 2This utility model provides a technical solution: a needle holder for general surgery, including a needle holder body 100, the needle holder body 100 including a needle handle 110, the needle handle 110 having two ends of the needle handle 110 being limited and locked with replacement clamping heads 120; the needle handle 110 includes an arc-shaped back plate 111, the two ends of the arc-shaped back plate 111 being respectively connected to clamping arms 112, the replacement clamping heads 120 being respectively installed on the clamping arms 112; the replacement clamping head 120 includes a clamping head 122, the clamping head 122 clamping the surgical needle, the outer end of the clamping head 122 being fixedly connected to a connecting cylinder 121, the connecting cylinder 121 being limited and connected to the end of the clamping arm 112, the needle handle 110 being integrally formed to avoid dead corners, making disinfection and sterilization more thorough, and avoiding cross-infection during later use.
[0029] Please see Figure 3 and Figure 4 The curved back plate 111 is C-shaped, and its two ends are fixedly connected to one end of the clamping arm 112, respectively. The clamping arm 112 is elastically connected to the curved back plate 111. A tapered head 113 is fixedly connected to the end of the clamping arm 112 away from the curved back plate 111, and a connecting rod 114 is fixedly connected to the other end of the tapered head 113. When the clamping arm 112 is gripped or squeezed, the curved back plate 111 will be compressed, making the clamping arm 112 elastic and easy to rebound.
[0030] Both the curved back plate 111 and the clamping arm 112 have rectangular cross-sections. The top view of the clamping arm 112 is an isosceles trapezoid, with the smaller end away from the curved back plate 111, making the component near the replacement clamping head 120 smaller and avoiding obstruction of the view. The tapered head 113 is rectangular at the end near the clamping arm 112, and circular at the end where it connects to the connecting rod 114. The two ends of the tapered head 113 transition smoothly, and the connecting rod 114 is a smooth cylinder. The smooth cylinder facilitates subsequent disinfection and also facilitates connection with the connecting cylinder 121.
[0031] A connecting sleeve 121 is fitted onto the outside of the connecting rod 114. A positioning bolt 125 is threaded through the top of the connecting sleeve 121, and the positioning bolt 125 abuts against the outer wall of the connecting rod 114. An extension sleeve 126 is fixedly connected to the outside of the connecting sleeve 121. The threaded part of the positioning bolt 125 is located inside the extension sleeve 126, and a screwing disc is provided on the top of the positioning bolt 125, located outside the extension sleeve 126. An extension head 123 is fixedly connected to one end of the clamping head 122. An anti-slip plate 124 is fixedly connected to the bottom of the clamping head 122 and the extension head 123. The anti-slip plate 124 has multiple sets of staggered V-shaped grooves for anti-slip purposes.
[0032] A limiting component 130 is connected to the middle of the needle-holding handle 110. The limiting component 130 includes a slide rod 131. One end of the slide rod 131 is fixedly connected to a limiting section 132, and the other end of the slide rod 131 is threaded with a limiting nut 133. The middle part of the slide rod 131 passes through the clamping arms 112. The middle part of the clamping arms 112 is provided with through-hole slots 115. The through-hole slots 115 are racetrack-shaped. The slide rod 131 is slidably disposed in the through-hole slots 115. By turning the limiting nut 133 at one end of the slide rod 131, the distance between the two clamping arms 112 can be further reduced, which facilitates the clamping of the surgical needle. At the same time, other simple and convenient components that reduce the stroke can be replaced, and the design can be customized as needed.
[0033] Working principle: Before the operation, medical staff select the appropriate replacement clamp head 120 according to the needs of the operation, and attach the connecting tube 121 to the outside of the connecting rod 114. By tightening the positioning bolt 125, the replacement clamp head 120 is limited and abutted against the outer wall of the connecting rod 114, thus completing the installation and fixation of the replacement clamp head 120.
[0034] During the operation, when it is necessary to adjust the travel between the two clamping arms 112, medical staff can turn the limiting nut 133. The limiting nut 133 compresses the clamping arms 112 to reduce the distance between the two clamping arms 112. Since the through-hole groove 115 is racetrack-shaped, the slide rod 131 can slide smoothly in it, avoiding jamming when compressing the clamping arms 112.
[0035] When using the needle holder body 100 to hold the surgical needle, the clamping head 122 secures the needle, and the anti-slip plate 124 increases friction to prevent the needle from slipping. After the surgery, loosen the positioning bolt 125, remove the used replacement clamping head 120 for disposal, and replace it with a new replacement clamping head 120 for use in the next surgery. The entire process is simple to operate and effectively meets the needs of using the needle holder during surgery, while reducing the risk of infection.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
