Abstract
The utility model discloses a circular anastomat nail anvil clamping forceps, including the centre gripping pincers body, the centre gripping pincers body includes left binding clip, right binding clip, semi-cylindrical's bayonet socket has all been seted up on left side binding clip, the right binding clip inner wall, left side binding clip, right binding clip clamp can make two bayonet socket cooperations form a cylinder hole, can encircle the clamp nail anvil head in the cylinder hole, but the fast and stable encircles nail anvil head center pole, can not drop and the horizontal hunting, and it is firm to grab and hold, and the operation visual angle is good, and the doctor's operation of being convenient for can accomplish the operation under less incision.
Description
Technical Field
The utility model relates to a centre gripping pincers, more specifically say a bit, relate to a circular anastomat nail anvil clamping pincers, belong to medical apparatus field.
Background
The circular anastomat most commonly used in the alimentary canal operation has the advantages that the diameter of a center rod of an anvil head is large, the existing surgical instruments are difficult to clamp, the neck of an esophagus stomach or the stomach and intestine of an open incision are anastomosed, the distance between an anastomotic stoma and the body surface is small, the anvil head of the anastomat is easy to place, however, the intrathoracic esophagus stomach anastomosis of the esophagus cancer resection operation or the esophagus stomach of the cardia cancer resection operation is difficult to place into the anvil head and the fixed nail anvil head through the esophageal fissure hole due to the deep anastomosis position, the existing instruments such as long-bend vascular forceps or right-angle forceps are difficult to place into the anvil head and the fixed nail anvil head, and particularly, the existing instruments are difficult to grasp the anvil head under the minimally invasive incision in recent years due to the rapid development of minimally invasive surgery, so that the operation time is prolonged, the possibility of stomach wall and esophageal mucosa injury can be.
SUMMERY OF THE UTILITY MODEL
In order to solve the prior art problems, the utility model provides a circular anastomat nail anvil clamping forceps which has the technical characteristics of simple structure, convenient operation, stable nail anvil clamping and the like.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the utility model provides a circular anastomat nail anvil clamping pincers, includes the centre gripping pincers body, the centre gripping pincers body includes left binding clip, right binding clip, all set up semi-cylindrical bayonet socket on left binding clip, the right binding clip inner wall, left binding clip, right binding clip clamp can make two bayonet sockets cooperation form a cylinder hole, can encircle the nail anvil head of clamp in the cylinder hole.
As an improvement, the inner wall of the bayonet is provided with a convex part for preventing skidding.
As an improvement, the clamping pliers body is a double-joint clamping pliers.
As an improvement, the left forceps head and the right forceps head are symmetrical and are bent at a certain angle relative to the main rod to form an arc shape.
As a refinement, the angle ranges from 120 ° to 135 °.
As an improvement, the cylindrical hole is matched with the size of the nail anvil head.
Has the advantages that: 1. compared with the existing bending pliers and other instruments, the two semi-cylindrical bayonets are designed according to the diameter of the center rod of the nail anvil head, and the anti-skid bulges are designed on the inner surfaces of the bayonets, so that the center rod of the nail anvil head can be exactly embraced, can not fall off and swing left and right, is firmly grasped, and is convenient to operate;
2. the left forceps head and the right forceps head are symmetrical and bent for a certain angle relative to the main rod to form an arc shape, the angle range is 120-135 degrees, the operation is more convenient relative to a 90-degree right angle or 180-degree straight rod, the view of a doctor is not blocked during deep operation of a thoracic cavity, and when the anvil head of the nail is butted, the distance between the arms of the holding forceps and the stomach wall is kept, so that accidental injury is avoided;
3. the forceps arms of the circular stapler nail anvil clamping forceps are designed in a double-joint mode, are more exquisite than conventional single-joint forceps, can complete operation under a smaller incision, and completely meet the requirements of esophagogastrostomy or intramediastinal anastomosis through esophageal fissure holes under an endoscope.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of a part of the structure of the present invention.
Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1-2, a specific embodiment of a circular stapler nail anvil clamping forceps includes a clamping forceps body, the clamping forceps body includes a left forceps head 1 and a right forceps head 2, and is characterized in that: all seted up semi-cylindrical bayonet socket 3 on left binding clip 1, the 2 inner walls of right binding clip, the clamping of left binding clip 1, right binding clip 2 can make two bayonet sockets 3 cooperation form a cylinder hole 4, can encircle in the cylinder hole 4 and press from both sides tight nail hammering block head, operation centre gripping pincers for two bayonet sockets 3 on left binding clip 1, the right binding clip 2 press from both sides tight nail hammering block head, and easy operation is convenient, and the practicality is strong, for adopting flat mouthful centre gripping pincers, more firm, can widen the design with left binding clip 1, right binding clip 2 end in order to match bigger bayonet socket 3 according to actual need, specifically adjust the design according to actual need.
As an improved embodiment mode, the inner wall of the bayonet 3 is provided with an anti-skid bulge, when the center rod of the nail anvil head is encircled, the friction force is increased by the bulge, the clamping is stable, the falling and the left-right swinging cannot occur, and the operation is convenient.
As an improved embodiment, the clamping forceps body is a double-joint clamping forceps, and the specific double-joint structure can be realized by adopting the Chinese patent application No. 201821074882.6, namely an operation structure recorded in the double-joint forceps, or by adopting a connecting rod, a spring and a pin shaft.
As an improved embodiment mode, the left forceps head 1 and the right forceps head 2 are symmetrical and are bent at a certain angle relative to the main rod 5 to form an arc shape, the operation is more convenient, the view of a doctor is not blocked during deep chest operation, and the distance between a holding forceps arm and a stomach wall is kept during butt nail anvil operation, so that accidental injury is avoided.
As a modified embodiment mode, the angle range is 120 degrees to 135 degrees, the angle is preferably 135 degrees, the specific angle can be adjusted according to actual needs, such as 120 degrees, 125 degrees, 130 degrees and the like, the operation is more convenient, the view of a doctor is not blocked during deep chest operation, and the distance between the holding forceps arms and the stomach wall is kept during anvil operation, so that accidental injury is avoided.
As an improved embodiment mode, the cylindrical hole 4 is matched with the nail anvil in size, so that when the left tong head 1 and the right tong head 2 are clamped, the two bayonets 3 on the left tong head 1 and the right tong head 2 just clamp the nail anvil, the structure is simple, and the practicability is high.
Finally, it should be noted that the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
