Description

Endoscopic cutting and clamping device

The invention provides an endoscope cutting and clamping device, in particular an endoscope cutting and clamping device with multi-angle adjustment to increase convenience.

According to press, modern medicine is more and more developed, so that the types of surgery are more and more, and more and more complicated. For example, minimally invasive surgery is a relatively common surgical method in modern times.

The so-called minimally invasive surgery is to use small incisions, small wounds, or organs on the patient, put the endoscope and auxiliary endoscope equipment to observe or cut the operation. Because the wound or incision is small, it has the advantages of reducing the patient's pain and the wound can heal faster.

In addition to the use of tubular endoscopes to observe the contents of the operation, some auxiliary tools need to be used to cut or remove the objects in the body (such as tumors or stones). However, because the internal structure of the human body is quite complicated, and the internal organs of the human body are quite fragile, in addition to multiple functions (such as clamping, cutting, etc.), the auxiliary tool also needs to have a multi-angle adjustment function to avoid the human body. Organs or some softer parts. Therefore, how to make the auxiliary tool have a multi-angle adjustment function is a problem that needs to be solved.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the one where the applicant of the present invention and related manufacturers engaged in this industry are eager to study the direction of improvement.

The first opening 42 is formed at the side of the first sleeve 41, the first sleeve 41 is pivotally arranged on the third connecting member 33, the first stopper 43 is telescopically arranged in the first sleeve 41, and is formed by the first The opening 42 is selectively penetrated, and one end of the first stopper 43 passing through the first sleeve 41 is pivotally arranged on the second pressure-extending and contracting member 5, and a plurality of first through holes 44 are formed on the first sleeve 41, Liquid or gas can be introduced into the first sleeve 41 to assist the first stopper 43 in the first sleeve 41 for telescopic movement. The second pressure-extending member 5 includes a second sleeve 51, a second opening 52, a second stopper 53, and a plurality of second through holes 54. The operation principle and structural relationship thereof are substantially the same as those of the first pressure-extending member 4, so they will not be repeated here. The only difference is that the first stopper 43 is connected to the second pressure-extending member 5, and the second stopper 53 is connected to the clamping element 6, and the third opening 71 is formed on the third sleeve 7, the third sleeve 7 is provided at the second opening 52 of the second pressure-extending member 5 so that the clamping element 6 can pass through the third opening 71.

In this embodiment, the clamping element 6 includes a first sheet body 64 and a second sheet body 65, one end of the first sheet body 64 is connected to one end of the second pressure expansion member 5, and the second sheet body 65 is Being pivotally arranged on the first sheet body 64, it can perform relative swinging movement with the first sheet body 64. The second sheet body 65 has a rope body 62, which can control the second sheet body 65 to approach the first sheet body 64 to grip the object. Moreover, there is an elastic element 61 between the first piece 64 and the second piece 65. If there is no need to grip, the first piece 64 and the second piece 65 can be separated by the elastic force of the elastic element 61. A spiral rotation auxiliary portion 63 is also formed on the first piece 64. The rotation auxiliary portion 63 has a spiral shape formed by twisting the first piece 64. The third opening 71 is a square opening matching the shape of the first body 64. When the second pressure-extending member 5 performs a telescopic movement and drives the clamping element 6 to move forward and backward, the rotation auxiliary portion 63 can be used to cooperate with the third opening 71 to rotate Clamping element 6.

The above-mentioned pivoting and pivoting are all formed by using holes and bolts in this embodiment, but the connection method is not limited.

Through the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of this structure, the first control member 1 and the second control member 2 can be used to drive the first connecting member 31 and the second connecting member 32 , And the third connecting member 33, and the first pressure expansion member 4 and the second pressure expansion member 5 can be controlled by gas or liquid, thereby increasing the swing angle of the clamping element 6, so that the user can use it more conveniently, The detailed explanation will be explained below.

Please also refer to the first figure to the sixth figure, which are the perspective perspective view to the action schematic diagram (4) of the preferred embodiment of the present invention. When the above components are assembled, it can be clearly seen from the figure that the use One can use the anti-slip portion 21 to assist in moving the first control member 1 and the second control member 2, thereby allowing the first control member 1 and the second connecting member 32 to slide on each other. And as shown in the third figure, when the second control member 2 moves backward based on the first control member 1, the first connecting member 31 will rotate counterclockwise with the first fulcrum 311 as the center, and the second connecting member 32 The second fulcrum 321 is used as the center of the circle to rotate counterclockwise. When the first connecting member 31 and the second connecting member 32 rotate counterclockwise, the third connecting member 33 is driven to swing clockwise. When the second control member 2 moves forward, the first connecting member 31, the second connecting member 32, and the third connecting member 33 move in opposite directions. As shown in the fourth figure again, the user can introduce liquid or gas into the first sleeve 41 through the first perforation 44 to control the first stopper 43 to telescopically move at the first opening 42 to thereby extend or Shorten the first pressure expansion member 4. When the first pressure-extending member 4 is extended, the second pressure-extending member 5 can be driven to swing in the counterclockwise direction with the third fulcrum 55 as the center, and if it is shortened, it swings in the clockwise direction. As shown in the fifth figure again, the second pressure-extending member 5 can also introduce liquid or gas into the second sleeve 51 through the second perforation 54 to control the second stopper 53 to expand and contract at the second opening 52 , Thereby extending or shortening the second pressure expansion member 5. When the second pressure expansion member 5 is extended or shortened, the clamping element 6 can be driven to move back and forth. When the clamping element 6 moves back and forth, the rotation assisting portion 63 performs a telescopic movement in the third sleeve 7. And when the rotation assisting portion 63 passes through the third opening 71, it will rotate the clamping element 6 through its spiral shape matching the shape of the third opening 71, so that the clamping element 6 can have a multi-angle swing function by the above-mentioned operation , Can increase the convenience of the present invention in use.

As shown in the sixth figure, when the user wants to grasp the object, the cord 62 can be pulled to drive the second piece 65 to swing clockwise, so that one end of the second piece 65 is close to the first piece 64 One end is used to grip the object. If it is relaxed, the second piece 65 will use the elastic force of the elastic element 61 to rotate counterclockwise to return to its original position.

Please also refer to the seventh figure at the same time, which is a three-dimensional perspective view of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is similar to the above embodiment, only in the first body A first cutting portion 641a is formed on the 64a, and a second cutting portion 651a is formed on the second piece 65a, and when the second piece 65a is driven against the first piece 64a via the rope 62a, it will be cut Objects, so that the clamping element 6a can have a shearing function.
