Embodiment 1

[0052] Reference manual attached Figure 1 to Figure 4 , the omnipotent hysteroscope provided by the present invention is described, and the channel sealing mechanism of the omnipotent hysteroscope provided by the present invention can be better when the working instrument 3 passes through, the working instrument 3 is replaced, and the working instrument 3 is missing. Reduce the outflow of liquid in the working pipeline, and keep the liquid pressure in the working pipeline in the range of 80-120mmHg during the use of the hysteroscope.

[0053] Reference manual attached figure 1 and figure 2 , The omnipotent hysteroscope provided by the present invention includes a hysteroscope main body 1 , a channel sealing mechanism 2 and a working instrument 3 . The hysteroscope main body 1 has a working pipeline 10; the working instrument 3 includes an instrument body and a working hand piece 32, and the working hand piece 32 is installed on the instrument body; the channel sealing mech...

Embodiment 2

[0081] Reference manual attached Figure 5 The second preferred embodiment of the channel sealing mechanism of the omnipotent hysteroscope provided by the present invention is described. The difference between the channel sealing mechanism of the omnipotent hysteroscope of the second preferred embodiment and the above-mentioned preferred embodiment is that , in the second preferred embodiment, further comprising a sleeve assembly installed on the working instrument 3, the sleeve assembly can prevent the working instrument 3 from The head end of 3 is in contact with the channel sealing mechanism 2, so that the head end of the relatively delicate working instrument 3 can be protected.

[0082] Reference manual attached Figure 5 , specifically, the omnipotent hysteroscope further includes a sleeve assembly 4, and the sleeve assembly 4 is adapted to be installed on the instrument body 31 of the working instrument 3 for 31 provides protection for the head end of the instrument b...

Embodiment 3

[0098] According to another aspect of the present invention, the present invention further provides a channel sealing method for the omnipotent hysteroscope, comprising:

[0099] During the process of inserting the working instrument 3 into the working pipeline 10, the elastic member 42 is pushed through the first locking part 51 of the working instrument 3 to drive the sleeve 41 located outside the working instrument 3 to move through together. channel sealing mechanism 2, and when the head end of the sleeve 41 passes through the channel sealing mechanism 2, the head end of the working instrument 3 is located in the sleeve 41; wherein the channel sealing mechanism 2 Located in the working pipeline 10;

[0100] When the head end of the sleeve 41 passes through the opening 20 of the sealing member 42 and moves a predetermined distance, it contacts the second locking part 52 installed in the working pipeline 10, allowing the working The instrument 3 continues to move forward re...

Abstract

The invention discloses an all-round hysteroscope, a working instrument and a channel sealing method. The working instrument comprises an instrument body with a first clamping part at the head end, and a sleeve assembly which is installed at the head end of the instrument body, wherein the sleeve assembly comprises a sleeve and an elastic piece; the sleeve surrounds to form an instrument channel;the instrument body is installed in the instrument channel; the first clamping part makes contact with the elastic piece and pushes the instrument body to move in the instrument channel relative to the sleeve, and the first clamping part can compress the elastic piece; when the compression amount of the elastic piece is smaller than or equal to a preset value, the head end of the instrument body is located in the instrument channel; and when the compression amount of the elastic piece is larger than the preset value, the head end of the instrument body extends out of the sleeve. The head end of the instrument body is kept in the sleeve in the stretching-in and withdrawing process, the head end of the working instrument is prevented from being damaged in the inserting and withdrawing process, and the head end of the instrument body is protected.

Description

technical field [0001] The invention relates to the field of hysteroscopy, and further relates to an all-round hysteroscope, a working instrument and a channel sealing method. Background technique [0002] Hysteroscopy is a surgical instrument used in gynecology. For all uterine space-occupying lesions, endometrial biopsy, adhesion release, mediastinal uterus, etc., hysteroscopy can be used for direct surgical treatment. At present, the surgical instruments used with hysteroscopy include electric cutter instruments, cold knife instruments, and planer knife systems. [0003] It should be pointed out that the head end of the existing all-round hysteroscope is easy to collide with structures such as the sealing valve of the pipeline wall during the process of instrument insertion and instrument replacement, which makes it easy to damage the delicate instruments during the instrument insertion and replacement process. damage to the head end. [0004] To sum up, it is necessary...
