Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially is concerned with a laparoscope puncture outfit of preventing misoperation. BACKGROUND

[0002] The laparoscope puncture outfit is an instrument in laparoscopic surgery. It is mainly used for establishing a channel on the abdominal wall, so that the laparoscope and other surgical instruments can enter the abdominal cavity, and can also maintain the gas pressure in the abdominal cavity.

[0003] Its use process is generally as follows: firstly, the puncture position on the patient's abdomen is selected and disinfected, then a small incision is made, the puncture cone of the puncture outfit is penetrated through the incision together with the puncture sleeve to penetrate the abdominal wall, the puncture needle is pulled out after entering the abdominal cavity, the laparoscope or surgical instrument is placed through the puncture sleeve to carry out surgery, and the puncture outfit is pulled out after the surgery is completed, and the incision is sutured.

[0004] In the prior art, in order to avoid the disconnection of the puncture cone and the puncture sleeve during the puncture process, a connecting mechanism is arranged to temporarily fix the puncture cone and the puncture sleeve, when the puncture cone needs to be withdrawn, the connecting relationship between the two is disconnected by pressing the button on the puncture cone, and then the puncture cone is withdrawn.

[0005] However, the connection mode has defects: during puncture, the operator needs to push the puncture outfit by holding the tail parts of the puncture cone and the puncture sleeve, and there is a risk of accidental pressing of the button during the pushing process, which may cause the puncture cone to be disconnected from the puncture sleeve in advance. INVENTION CONTENTS

[0006] The utility model aims at solving one of the technical problems existing in the prior art. Therefore, one purpose of the utility model is to provide a laparoscope puncture outfit capable of preventing misoperation. The structure for releasing the connection relationship between the puncture cone and the puncture sleeve in the puncture outfit no longer uses the button mode in the traditional structure, which can prevent the puncture cone and the puncture sleeve from being disconnected due to accidental pressing of the button during the puncture process, and has the advantage of safer puncture process.

[0007] According to the laparoscope puncture outfit capable of preventing misoperation provided by the utility model, the puncture sleeve comprises a tube body and a head part formed at one end of the tube body, a sealing seat is installed on the head part, the puncture cone comprises a cone body and an end seat formed at one end of the cone body, the cone body can penetrate the tube body through the sealing seat and the head part, and the puncture cone and the puncture sleeve both adopt the traditional structure, and the sealing seat is buckled on the head part.

[0008] Different from the traditional scheme, the hook member is formed on the end seat near the sealing seat in the puncture device, the corresponding position of the sealing seat is formed with a groove for the hook member to extend into, and a column groove is formed on the sealing seat and communicates with the groove, one end of the column groove extends to the outside of the sealing seat, the first pin member and the elastic member are arranged in the column groove, the elastic member abuts against the stop formed by the first pin member and the column groove, the transmission member is connected to the first pin member, and the transmission member extends to the outside of the sealing seat through the column groove, so that the first pin member can produce linear reciprocating motion along the column groove under the transmission of the transmission member and the restoring deformation of the elastic member.

[0009] When the elastic member is in a free state, the main body of the first pin member is also located in the column groove, one end of the main body extends into the groove, and the first pin member can fix the hook member extending into the groove, thereby connecting the puncture cone and the puncture sleeve; when it is required to separate the puncture cone from the puncture sleeve, an external force is applied to the transmission member to drive the first pin member to displace into the column groove, and the puncture cone can be removed, at this time, the elastic member is compressed, and the first pin member is reset under the deformation of the elastic member after the puncture cone is removed.

[0010] In the process, the external force acting on the transmission member can be pulling or rotating, and both the two force applying modes are inconsistent with the placement action of the puncture device, so that misoperation cannot occur

[0011] In some examples of the utility model, the transmission member is a rope body, one end of the rope body is connected with the first pin member, and the other end of the rope body is connected with the rotating operation knob arranged on the sealing seat.

[0012] In this way, when the force is applied to the rope body, the operation knob only needs to be rotated, the rotating action is inconsistent with the placement action of the laparoscope puncture device, misoperation cannot occur, and the utility model is convenient to use.

[0013] In some examples of the utility model, the operation knob is a ring member, and the ring member is rotatably connected to the sealing seat, so that the ring member does not occupy too much space on the sealing seat.

[0014] In some examples of the utility model, a step is formed on the sealing seat, one end of the operation knob abuts against the step, and the step is used to form a stop action on the operation knob to prevent the operation knob from moving away from the sealing seat.

[0015] In some examples of the utility model, a stop ring is further arranged on the side of the operation knob away from the step, the stop ring is connected to the sealing seat, and the stop ring is also used to form a stop action on the operation knob to prevent the operation knob from moving away from the sealing seat at the other end.

[0016] In some examples of the utility model, the stop is a second pin member which is connected to the sealing seat and penetrates through the column groove.

[0017] In some examples of the utility model, a through hole is formed in the part of the second pin member located in the column groove, and the rope body can pass through the through hole.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
