Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a needle holding forceps with stable clamping. Background Art

[0002] Needle holder is a kind of medical instrument, which is mainly used for clamping and transferring suture needles during surgery. Its front end is usually designed to be curved and with a small tip, so as to clamp the suture needle accurately and stably, and prevent medical staff from directly contacting the needle and causing accidental injury. At the same time, it can also improve the accuracy of surgical operation. Needle holder is generally made of stainless steel, which is corrosion-resistant and easy to disinfect, and meets the aseptic requirements in medical environment. Most of the existing needle holders are of straight grip type, which can meet the requirements for suturing in external wounds, but when suturing some organs, the field of view of the incision is limited, and the straight grip method will block the field of view, which will affect the suturing. At the same time, the needle holder clamps the suture needle by manually applying force. In some surgical procedures, the needle needs to be clamped for a long time for surgery, so continuous force needs to be applied. The hands are prone to fatigue over a long period of time, which will not only affect the surgical operation, but also cause the suture needle to be unstable and easy to fall. Utility Model Content

The handle can be bent and adjusted by a bending component, so that the angle of the handle can be adjusted by 180° to adapt to various surgical operations. The bending of the handle can avoid the hand blocking the field of vision, and the needle holder can be held more comfortably during the operation. Secondly, the clamping state of the needle holder can be fixed by the locking component, and the user does not need to continuously apply force to clamp the needle, which makes the needle holder clamp more firmly, effectively reduces hand fatigue and prevents the surgical needle from falling off.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] The firmly clamping needle holding forceps is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] See also Figure 1-7 In the embodiment, a needle holding forceps with stable clamping is provided, comprising: a handle a1, one side of the handle a1 is rotatably connected to a handle b11, one end of the handle a1 and the handle b11 are respectively fixedly connected to matching jaws a12 and jaws b13, the other ends of the handle a1 and the handle b11 are respectively rotatably connected to handles 14, one end of the two handles 14 are respectively fixedly connected to symmetrically arranged finger rings 15, a bending assembly, the bending assembly is respectively on the two handles 14, and is used to adjust the inclination angle of the two handles 14, and a locking assembly, the locking assembly is arranged on the handle b11, and is used to fix the opening and closing angles of the jaws a12 and jaws b13.

[0027] Among them, the handle can be bent and adjusted through the bending component, so that the angle of the handle can be adjusted 180°, which can adapt to a variety of surgical operations. The bending of the handle can prevent the hand from blocking the field of vision, and the needle holder can be held more comfortably during the operation;

[0028] Secondly, the locking component can fix the clamping state of the needle holder, eliminating the need for the user to continuously apply force to clamp the needle, making the needle holder more secure, effectively reducing hand fatigue and preventing the surgical needle from falling off.

[0029] Example 2

[0030] On the basis of Example 1, the bending assembly includes: through holes 2 respectively opened at the two handles 14 and the connection between the clamp handles a1 and b11, a moving rod 21 is slidably connected inside the through hole 2, a button 22 is connected to one end of the moving rod 21, the other end of the moving rod 21 is fixedly connected to a limiting plate 23, a plurality of fixed rods 24 are fixedly connected to the side of the limiting plate 23 close to the handle 14, the plurality of fixed rods 24 are distributed in a circular array, and fixing holes 25 for matching with the plurality of fixed rods 24 are respectively opened at the connection between the handle 14 and the clamp handle b11, a gasket 26 is sleeved on the outside of the moving rod 21, a spring 27 is connected between the two washers 26, and the spring 27 is sleeved on the outside of the moving rod 21.

[0031] In delicate surgical operations, it is necessary to clamp a suture needle for operation. Holding the needle forceps straight for a long time will not only make the hands very tired, but also in some specific surgical operations, the hands holding the needle forceps straight will block the line of sight and be detrimental to observation. At this time, by manually pressing the button 22, the button 22 pushes the washer 26 to move closer to the other washer 26 when it moves, so that the spring 27 is squeezed and contracted to store energy, thereby pushing the moving rod 21 to slide inside the through hole 2. The moving rod 21 simultaneously pushes the limit plate 23 to move. The limit plate 23 can limit the moving distance of the moving rod 21. The limit plate 23 drives the fixing rod 24 to move, so that the fixing rod 24 withdraws from the fixing hole 25, thereby releasing the fixing restriction on the handle 14, and then bending the handle 14 to adjust it to a suitable tilt angle, and then releasing the button 22. The spring 27 releases its elasticity after losing the pressure, thereby pushing the button 22 to the other end, and the moving rod 21 drives the limiting plate 23 to move accordingly. The limiting plate 23 inserts the fixing rod 24 into the fixing hole 25, and then fixes the handle 14. In this way, the angle of the handle 14 can be adjusted, so that the holding method can be changed, and the hand is prevented from blocking the field of vision and affecting the surgical operation.

[0032] Example 3

[0033] On the basis of Example 1, the locking assembly includes: a friction ring 3 arranged on the pliers handle a1 at a position close to one side of the pliers handle b11, a threaded hole 31 is opened on the pliers handle b11 at a position corresponding to the friction ring 3, a threaded rod 32 threadedly connected to the inside of the threaded hole 31, a friction block 33 at one end of the threaded rod 32 close to the friction ring 3, a rotating disk 34 is fixedly connected to the end of the threaded rod 32 away from the friction block 33, and a paddle 35 is fixedly connected to the other side of the rotating disk 34.

[0034] After clamping the suture needle, the hand grasps the paddle 35 and rotates clockwise, and the paddle 35 drives the rotating disk 34 to rotate, and the threaded rod 32 is also driven to rotate during the rotation. When the threaded rod 32 rotates, it screws into the threaded hole 31, and then drives the threaded rod 32 to move to one side of the friction ring 3, and continues to rotate until the friction block 33 at one end of the threaded rod 32 hits the friction ring 3, and then the clamping state of the jaws a12 and b13 can be fixed, so that there is no need to continuously apply force to clamp the suture needle during surgery, and the suture needle can be clamped stably, avoiding hand fatigue caused by manual force clamping, resulting in unstable clamping of the suture needle and the problem of the suture needle falling off.

[0035] Among them, a number of clamping grooves 16 are respectively opened on the opposite sides of the pliers mouth a12 and the pliers mouth b13, and anti-slip grooves are respectively opened on the inner walls of the clamping grooves 16. The clamping grooves 16 are equidistant from left to right in a straight line from small to large. The clamping grooves 16 can clamp suture needles of different thicknesses, and the anti-slip grooves on the inner walls can increase friction to prevent the suture needle from sliding.
