Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the present invention.
A clamping traction apparatus is a wiring type tissue traction apparatus set for a nasal and cranial endoscopic surgery in the embodiment, and comprises two sets of oppositely arranged clamping parts 1, wherein one end of each clamping part 1 is provided with a clamping end 2. The instrument also comprises an elastic part which drives the two groups of clamping parts 1 to swing and leads the two corresponding groups of clamping ends 2 to be attached and clamped; the connecting piece is used for connecting an external operation instrument.
Further, in this embodiment, the elastic portion includes two sets of elastic pieces 3, one end of each elastic piece 3 is a fixed end 5, the other end is a connecting end 4, and the two fixed ends 5 are fixedly connected to each other. Two link 4 alternating expression respectively with the end connection of two sets of clamping parts 1, the elastic component is the pressurized form, and elastic potential energy orders about two link 4 and outwards opens, drives two sets of clamping ends 2 and pastes the clamp tightly mutually.
Exemplarily, the elastic part is when not receiving other external forces, and two sets of shell fragment 3 outwards expand under the effect of elastic force, and because of the link 4 of two sets of shell fragment 3 is the alternating expression again and is connected with two sets of clamping parts 1, so two sets of shell fragments 3 will reverse order about two sets of clamping parts 1 to the direction swing that is close to each other, and it is tight to paste till two sets of clamping parts 2, realizes pressing from both sides the effect of tight tissue. In addition, when the clamping end 2 in the clamping state needs to be opened, only two groups of elastic sheets 3 need to be pressed simultaneously, and the two groups of elastic sheets 3 are pressed inwards under the action of overcoming the elastic force, so that the two groups of elastic sheets 3 are close to each other, and at the moment, the elastic sheets 3 drive the two groups of elastic sheets 3 to swing reversely through the clamping part 1, so that the effect of opening the clamping end 2 is realized.
Preferably, in this embodiment, in order to press the two sets of elastic pieces 3, a protrusion 6 is disposed on one side of the elastic piece 3 close to the connecting end 4. Therefore, when the loosening or clamping state of the clamping end 2 needs to be adjusted, the bulge 6 only needs to be pressed or loosened.
More preferably, in this embodiment, the connector comprises a ring 7, and the ring 7 is fixedly arranged at the fixed end 5. It should be noted that, after the instrument clamps the tissue, by tying the suture on the ring 7, the operator can achieve the effect of pulling the tissue by pulling the suture on the outside.
The invention aims to design a group of surgical intraluminal tissue traction and matched retraction and extension instruments. The auxiliary hand-held clamping instrument saves the occupied space of the original hand-held clamping instrument in the operation cavity, and simultaneously, the auxiliary hand is used for remotely pulling the pathological changes or other tissues, thereby achieving the purposes of assisting the operator to expose the boundary of the pathological changes or important anatomical structures and widening the operation space of the operator.
The specific working process is as follows:
when operating this apparatus, hang 0 number operation suture by operating personnel on tractive apparatus terminal ring 7 after, go into tractive apparatus card and receive and release the apparatus, send into art chamber assigned position by operating personnel, thereby press from both sides tight arch 6 and open and press from both sides tight end 2, after finding the tissue position that needs carry out the tractive, loosen the handle that receives and releases the apparatus, shell fragment 3 at this moment under the effect of elasticity reverse order about two sets of clamping parts 1 to the direction swing that is close to each other, it is tight to paste tightly until two sets of tight ends 2 of clamp, the effect of the tight tissue of realization clamp. At the moment, the operation of clamping the tissues is finished, the tail end of the surgical suture is left outside the surgical cavity, and the operator carries out the remote traction operation by holding the suture. After the pulling operation is finished, the surgeon loosens and takes out the surgical instrument by the retraction instrument.
It should be noted that, in the present embodiment, the clamping end 2 includes a flat clamp, and the flat clamp is integrally provided with the clamping portion 1. In this embodiment, the flat clamp arrangement is suitable for less tissue clamping and pulling.
Example 2:
fig. 2 and fig. 3 are diagrams illustrating a specific structure of the clamping end 2 in an embodiment of the present invention, and fig. 3 is a schematic diagram illustrating a bent state structure of the clamping end 2 in an embodiment of the present invention.
The present embodiment differs from embodiment 1 in that in the present embodiment, the clamping end 2 is provided bent 45 ° to one side. The angled clamping end 2 can clamp and draw a smaller amount of tissue in the middle of a non-operative cavity in a narrower operative cavity in the endoscopic nasal surgery.
Example 3:
referring to fig. 4, fig. 4 is a schematic structural diagram of the clamping end 2 with saw teeth according to the embodiment of the present invention.
The present embodiment differs from embodiment 1 in that in the present embodiment the clamping surface of the clamping end 2 is provided with serrations. The arrangement of the sawteeth increases the overall friction of the clamping end 2, and is suitable for clamping and drawing tougher tissues when larger clamping and drawing force is needed.
Example 4:
referring to fig. 5, fig. 5 is a schematic diagram showing a specific structure of the clamping end 2 of the bandwidth head clamp according to the embodiment of the present invention.
The present embodiment is different from embodiment 1 in that, in the present embodiment, the clamping end 2 includes a wide head clip, which is protrudingly provided to the clamping portion 1. The design of the wide-head clamp increases the whole clamping area of the clamping end 2, so that the amount of tissues which can be clamped is increased, and the whole application range of the traction apparatus is expanded.
Example 5:
referring to fig. 6, fig. 6 is a schematic diagram showing a specific structure of the clamping end 2 with the through hole 8 in the embodiment of the present invention.
The difference between this embodiment and embodiment 1 is that in this embodiment, the middle of the clamping end 2 is provided with a through hole 8. When the through hole 8 is arranged, the clamping end 2 can clamp the tissue, the tissue can sink into the through hole 8 and protrude out of the through hole, the overall traction force is greatly improved, and the clamping traction device is suitable for clamping and traction of a tougher tissue when large clamping traction force is needed.
Example 6:
referring to fig. 7, fig. 7 is a schematic view showing a specific structure of the clamp end 2 of the embodiment of the present invention.
The present embodiment differs from embodiment 1 in that in the present embodiment the clamping surface of the clamping end 2 is arranged concavely. In this embodiment, the radian of the clamping surface is increased at the clamping end 2, so that the clamping and pulling force is improved, and the supportable clamping and pulling force is higher, so that the clamping and pulling device is suitable for clamping and pulling of a tougher tissue when a larger clamping and pulling force is needed.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
