Description

Technical Field

[0001] The utility model relates to an endoscope component, in particular to a limiting block adapted for an endoscope. Background Art

[0002] An endoscope is a commonly used medical device, which consists of a head, a bending part, an insertion part, an operating part, and a light-guiding part. When in use, the light-guiding part of the endoscope is first connected to a matching cold light source, and then the insertion part is introduced into the organ to be pre-examined. The operating part can be controlled to directly observe the lesions in the relevant parts; or other tools can be guided into the body through the endoscope for surgery, such as soft tissue clamps, foreign body forceps and other tools that enter the body through the insertion part of the endoscope for surgery. However, when using the above tools, the extension length of the tools after passing through the insertion part is uncontrollable or not fixed, which makes the operation difficult for medical staff and even causes discomfort to patients.

[0003] like Figure 1 As shown, after the catheter 201 of the soft tissue clamp 200 passes through the insertion portion 102 of the endoscope 100, since the catheter 201 is not limited at the clamp opening 101, the extended length of the catheter 201 at the tail of the insertion portion 102 is uncontrollable, which is not conducive to medical personnel performing surgery on the target position through the soft tissue clamp. If the medical personnel repeatedly pulls the catheter to find the target position, it will cause discomfort to the patient, resulting in resistance or non-cooperation of the patient; or after the medical personnel finds the target position, if the extended length of the catheter 201 is not fixed, it is also inconvenient for the medical personnel to work. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides a limit block adapted for an endoscope, which is fixed to the catheter of a tool (such as a soft tissue clamp, a foreign body forceps or other workpieces that enter the body through an endoscope) by a snap-fit ​​installation method, and the limit block is further limited to the forceps opening of the endoscope, thereby fixing the protruding length of the catheter at the tail of the insertion part, thereby facilitating medical personnel to operate on the target position in the body through the workpiece.

[0005] Specifically, a limit block adapted for an endoscope is provided with a clamping groove, the clamping groove is clamped and fixed to a catheter of an action member, and the limit block is limited to a clamp channel opening of the endoscope;

[0006] The acting member is a tool that acts on internal tissues of the body through an endoscope, and the catheter is a portion of the tool that passes through an insertion portion of the endoscope.

[0007] The above-mentioned technical features can realize the extension length of the fixed catheter at the tail of the insertion part, thereby facilitating medical personnel to operate the target position in the body through the workpiece; the limit block is connected to the catheter by means of the locking groove, which can facilitate the staff to quickly connect or separate the limit block from the catheter.

[0008] In order to prevent medical personnel from installing the limit block axially, because axial installation (for example, the limit block is installed from the tail end of the catheter and then moved upward) is relatively complicated and easy to contaminate the catheter or the working part of the tail end of the catheter; optionally, an axially extending notch is opened on one side of the limit block, and the diameter of the notch is larger than the external connection of the catheter. Through this technical feature, medical personnel can radially install or remove the limit block.

[0009] In order to make the limit block better fit with the jaw opening, optionally, the limit block includes an insert body, which is fitted with the jaw opening, and the engaging groove and the notch both axially penetrate the insert body. When in use, the insert body is formed of a soft material, at least a portion of which is inserted into the jaw opening, and can be fixed by interference fit, thereby achieving the fit between the insert body and the jaw opening. After the limit block is fixed, the extended length of the catheter engaged with the limit block is also fixed.

[0010] In order to facilitate the removal of the insertion part from the clamp opening or prevent the entire insertion part from falling into the clamp opening, optionally, a limiting part is provided on the upper part of the insertion body, which can be a protrusion extending outward from the upper edge of the insertion body, or a disc coaxial with the insertion body.

[0011] In order to facilitate the insertion body to better adapt to the forceps opening, optionally, the lower portion of the insertion body has a conical surface.

[0012] The utility model has the following advantages:

[0013] The utility model has reasonable design and is easy to use. It is a limit block adapted for an endoscope. The limit block is fixed to the catheter of a tool (such as a soft tissue clamp, a foreign body forceps or other workpieces that enter the body through an endoscope) by a snap-fit ​​installation method. The limit block is further limited at the clamp channel opening of the endoscope, thereby fixing the extended length of the catheter at the tail of the insertion part, thereby making it convenient for medical personnel to operate on the target position in the body through the workpiece.

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0025] As described in the background technology, Figure 1As shown, after the catheter 201 of the soft tissue clamp 200 passes through the insertion portion 102 of the endoscope 100, since the catheter 201 is not limited at the clamp opening 101, the extended length of the catheter 201 at the tail of the insertion portion 102 is uncontrollable, which is not conducive to medical personnel performing surgery on the target position through the soft tissue clamp. If the medical personnel repeatedly pulls the catheter to find the target position, it will cause discomfort to the patient, resulting in resistance or non-cooperation of the patient; or after the medical personnel finds the target position, if the extended length of the catheter 201 is not fixed, it is also inconvenient for the medical personnel to work.

[0026] Based on the above reasons, Figure 1-Figure 5 As shown, this embodiment provides a stopper block 300 adapted to the endoscope 100, the stopper block is provided with a snap-fitting groove 303, the snap-fitting groove is snap-fitted and fixed to the catheter 201 of the action member, and the stopper block is limited to the forceps opening 101 of the endoscope 100;

[0027] The action member is a tool that acts on the internal tissue of the body through the endoscope 100 (such as a soft tissue clamp 200, a foreign body forceps or other workpieces that enter the body through the endoscope to act on the body), and the catheter is the part of the tool that passes through the endoscope insertion part 102 (such as Figure 1 as shown).

[0028] The above technical features can realize the extension length of the fixed catheter at the tail of the insertion part, thereby facilitating medical personnel to operate the target position in the body through the workpiece; the limit block is connected to the catheter by means of the locking groove, which can facilitate the staff to quickly connect or separate the limit block from the catheter.

[0029] In order to prevent medical staff from installing the stopper block axially, because axial installation (for example, the stopper block is installed from the tail of the catheter and then moved upward) is more complicated and easy to contaminate the catheter or the working part of the tail of the catheter; Figure 4-Figure 8 As shown, an axially extending notch 305 is provided on one side of the limit block 300 , and the diameter of the notch 305 is larger than the external connection of the catheter 201 . This technical feature enables medical personnel to radially install or remove the limit block 300 .

[0030] In order to make the stop block and the opening of the clamp better fit, in one embodiment, the stop block 300 includes an insert body 302, which is adapted to the clamp channel 101, and the engaging groove and the notch 305 both axially penetrate the insert body. When in use, the insert body is formed of a soft material, at least a portion of which is inserted into the opening of the clamp channel, and can be fixed by interference fit, thereby achieving the fit of the insert body and the opening of the clamp channel. After the stop block is fixed, the extended length of the catheter engaged with the stop block is also fixed.

[0031] In another embodiment, the limit block 300 includes an insert body 304, which is inserted into the clamp channel 101, and a limit portion 301 is provided on the upper part of the insert body 304. The limit portion 301 can be a protrusion extending outward from the upper edge of the insert body, or a disc coaxial with the insert body; preferably, the limit portion is a disc, and the outer diameter of the limit portion is greater than the diameter of the clamp channel opening; the engaging groove and the notch both axially penetrate the limit portion and the insert body. The limit portion facilitates the removal of the insert portion from the clamp channel opening or prevents the entire insert portion from falling into the clamp channel opening.

[0032] In order to facilitate the insertion body to better fit the forceps opening, optionally, the lower portion of the insertion body has a conical surface 304.

[0033] The limit block of the utility model is fixed to the catheter of a tool (such as a soft tissue clamp, a foreign body forceps or other workpieces that enter the body through an endoscope) by a snap-fit ​​installation method. The limit block is then limited to the forceps opening of the endoscope, thereby fixing the extended length of the catheter at the tail of the insertion part, thereby facilitating medical personnel to operate on the target position in the body through the workpiece.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
