Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel suture needle holder. Background Art

[0002] Medical equipment refers to instruments, equipment, appliances, materials or other items used on the human body alone or in combination, and also includes the required software. Medical equipment is the most basic element of medical treatment, scientific research, teaching, institutions, and clinical disciplines, and includes both professional medical equipment and home medical equipment.

[0003] In clinical surgery, needle holders are used for suturing operations. However, due to the deep location of some surgical sites and the narrow operating space, traditional needle holders are not convenient to use or are not conducive to the completion of suturing operations, such as uvulopalatopharyngoplasty. To this end, we provide a new type of suturing needle holder to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a novel suture needle holder. The forceps head has a certain angle, and the angle of the forceps head can be adjusted according to surgical requirements, which is convenient to use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of suture needle holder, comprising a clamp handle, wherein the jaw end of the clamp handle is provided with an angle-adjusting clamp head mechanism, the angle-adjusting clamp head mechanism comprises a clamp head arranged at the jaw, a hollow hole is opened on one side of the upper surface of the clamp head, two hollow shaft columns are fixedly connected to the jaw of the clamp handle, the hollow holes are sleeved on the outside of the hollow shaft column, and the hollow holes are rotatably connected to the hollow shaft column.

[0006] Furthermore, a slidable movable ring is provided inside the hollow shaft column, a pull rod is fixedly connected to the upper surface of the movable ring, and a telescopic spring is wound on the outer surface of the pull rod, the top of the pull rod passes through the hollow shaft column and extends to the outside of the hollow shaft column, the top of the pull rod is fixedly connected to a pressure plate, and the bottom surface of the pressure plate is fixedly connected to a pressure ring. After the angle adjustment of the clamp head is completed, the medical staff can pull the pressure plate to make the pressure plate drive the pressure ring to move upward, and then release the pressure plate. The telescopic spring pushes the movable ring and the pull rod to move downward, the pull rod drives the pressure plate and the pressure ring to move downward, and the pressure ring pushes the insertion rod to insert into the inside of the socket, thereby limiting and fixing the clamp head to prevent the clamp head from swinging during use.

[0007] Furthermore, the pressure ring is sleeved on the outer surface of the hollow shaft column, and the pressure ring is slidably connected to the outer surface of the hollow shaft column. The pressure ring can slide back and forth on the outer surface of the hollow shaft column, and at the same time effectively avoids the pressure ring from being stuck on the outer surface of the hollow shaft column due to friction or angle deviation, thereby affecting the normal use of the needle holder.

[0008] Furthermore, the bottom surface of the pressure ring is fixedly connected with a ring-shaped array of insertion rods, and the upper surface of the clamp head is provided with a socket adapted to the insertion rods. The position of the clamp head is further fixed by inserting the insertion rods into the sockets.

[0009] Furthermore, the side surfaces of the two clamp heads that are close to each other are fixedly connected to a clamping plate, and the side surfaces of the two clamping plates that are close to each other are fixedly connected to anti-skid ribs arranged at equal distances. The mutual engagement of the anti-skid ribs can effectively increase the friction force of the clamping plate when clamping the needle, thereby improving the clamping effect on the needle and preventing the suture needle from being deflected, which affects the suture operation.

[0010] Furthermore, a baffle rod is fixedly connected to the side surfaces of the two pliers handles that are close to each other, and the positions of the two baffle rods correspond to each other. When the two pliers handles are closed, the two baffle rods can block and limit each other to avoid the connection between the two pliers handles, which may cause the two pliers handles to clamp foreign objects or injure the fingers of medical staff at the contact position.

[0011] Furthermore, the ends of the two pliers handles that are away from each other are fixedly connected to a holding ring, and the side surfaces of the two pliers handles that are close to each other are provided with an arc groove, so that there is a certain gap at the contact position of the two pliers handles, effectively preventing the medical staff's hands from being accidentally pinched when the pliers handles are closed.

[0012] Compared with the prior art, the new suture needle holder has the following beneficial effects:

[0013] 2. The utility model pushes the movable ring downward through the telescopic spring, and the movable ring drives the pressure plate and the pressure ring to move downward through the pull rod. The pressure ring pushes the insertion rod to insert into the inside of the socket on the clamp head, thereby completing the angle adjustment of the clamp head, so that the angle of the clamp head of the needle holder can be adjusted according to the surgical requirements, which is convenient to use.

[0014] 2. The utility model can effectively increase the friction force of the clamping plate when clamping the needle and improve the clamping effect on the needle by setting the clamping plate and the anti-skid ribs and utilizing the mutual engagement of the anti-skid ribs, thereby avoiding the suture needle from being deflected and affecting the suturing operation. By setting the baffle rod, when the two clamp handles are closed, the two baffle rods can block and limit each other to avoid the connection between the two clamp handles, resulting in the two clamp handles contacting The position clamping foreign objects or pinching the fingers of medical staff. By setting the arc groove, a certain gap exists at the contact position of the two clamp handles, which effectively avoids the medical staff's hands being pinched accidentally when the clamp handles are closed.

[0022] See also Figures 1 to 4 This embodiment proposes a new type of suture needle holder, including a clamp handle 1, and a baffle rod 5 is fixedly connected to the side of the two clamp handles 1 that are close to each other. The two baffle rods 5 are in corresponding positions. When the two clamp handles 1 are closed, the two baffle rods 5 can block and limit each other to avoid the connection between the two clamp handles 1, which may cause the two clamp handles 1 to clamp foreign objects at the contact position or injure the fingers of medical staff.

[0023] Reference Figure 1 The ends of the two pliers handles 1 that are away from each other are fixedly connected with a holding ring 4, and the sides of the two pliers handles 1 that are close to each other are provided with an arc groove 3, so that there is a certain gap at the contact position of the two pliers handles 1, which effectively prevents the medical staff's hands from being pinched accidentally when the pliers handles 1 are closed.

[0024] The outer surface of the grip ring 4 can be selectively provided with a protective groove, so that when the medical staff holds the grip ring 4, the friction between the hand and the grip ring 4 can be effectively increased to avoid hand slipping during use.

[0025] An angle-adjustable clamp head mechanism 2 is provided at the jaw end of the clamp handle 1 , and the angle-adjustable clamp head mechanism 2 includes a clamp head 207 provided at the jaw end.
