Description

Rectal prolapse measuring instrument

Technical Field

The invention relates to the field of medical instruments, in particular to a rectal prolapse measuring instrument.

Background

The rectal wall is displaced partly or wholly downwards, called rectal prolapse (rectal prolapse). The rectal wall portion moves down, i.e., the rectal mucosa moves down, called a mucosa prolapse or incomplete prolapse; full-layer inferior movement of the rectal wall is called complete prolapse. If the moved down rectal wall is in the anorectal cavity, the rectal wall is called as an internal prolapse; the downward movement out of the anus is called prolapse.

The main clinical symptoms of rectal prolapse are the prolapse of the tumor from the anus. The swelling is smaller at the initial stage, the swelling is separated at the defecation stage, and the swelling is reset after defecation. The swelling is released gradually, the volume is increased, and the swelling is required to be held back into the anus after defecation, with the symptoms of incomplete defecation and falling. Finally, the cough and the forceful standing can be removed. With prolapse aggravates, anal incontinence of varying degrees is caused, and mucous is often shed, resulting in perianal skin eczema and itching. Constipation often occurs due to the difficulty in emptying the rectum, and the number of times of defecation is increased, and the sheep manure is present. The mucous membrane is eroded, and blood flows out after the mucous membrane is broken.

Symptoms are not obvious when the internal prolapse is caused, and the symptoms are mainly symptoms of the abnormal defecation, the obstruction of anus and other rectal emptying disorders. The suppository is inserted into anus to assist defecation, so that defecation becomes smooth. Some patients have lower abdominal and lumbosacral distending pain during bowel movements. Longer periods of illness can also cause varying degrees of anal incontinence.

The existing method for checking rectal prolapse in clinic mainly comprises the following steps: 1. digital diagnosis of rectum: mainly feeling the contractive force of the anal sphincter; 2. defecation contrast examination: specific symptoms on the defecation radiography X-ray film characterize the severity of rectal prolapse; 3. anoscopy: the condition of the rectal mucosa is directly observed, but since the anoscopy needs to support the intestinal cavity with air for observation, the prolapse and folding state is destroyed, cannot be detected, and only the surface condition of the rectum can be seen. None of the above three methods allow quantitative analysis of rectal prolapse.

The description of these embodiments is provided to assist understanding of the present invention, but is not intended to limit the present invention. In addition, technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

The present embodiment provides a rectal prolapse meter that can be accessed into the rectum to quantitatively measure prolapsed tissue. Referring to fig. 1 to 5, the rectal prolapse measuring instrument includes a housing 1, an endoscope 6, a housing mechanism for housing prolapsed tissue, and a driving mechanism for driving the housing mechanism to open or close. For ease of understanding and description, the end of the rectal prolapse meter and its components that is closer to the prolapsed tissue to be measured is defined as the distal end (e.g., corresponding to the left side of the paper in fig. 1), whereas the end that is closer to the doctor's hand is the proximal end (e.g., corresponding to the right side of the paper in fig. 1); i.e. the rectal prolapse meter and its components have a distal end corresponding to the prolapsed tissue and a proximal end opposite said distal end. The terms "inner" and "outer" are defined herein with reference to the axis of the outer tube, and are inner on the side closer to the axis of the outer tube, and outer on the opposite side.

The housing 1 is formed by fixedly connecting two parts of shells through screws and the like for being held by hands of people for convenient operation, wherein an inner cavity for arranging other parts is also formed. The distal end portion of the housing 1 has an outer tube 2, and the outer tube 2 is hollow and fixedly connected or integrally formed with the housing 1.

The housing mechanism includes a plurality of housing members 3, a proximal end portion of each housing member 3 being rotatably connected to a distal end portion of the outer tube 2, the plurality of housing members 3 being arranged in a circumferential direction of the outer tube 2 to form a housing that can house prolapsed tissue. The plurality of chamber elements 3 are rotatably connected to the distal end of the outer tube 2, respectively, in particular by means of a first fixing ring 21. As shown in fig. 4, six cavity members 3 are arranged at equal intervals in the circumferential direction of the outer tube 2; as shown in fig. 1 to 3, the first fixing ring 21 is fixedly sleeved on the distal end portion of the outer tube 2 along the circumferential direction of the outer tube 2, and the inner end portion of the cavity member 3 is rotatably sleeved on the first fixing ring 21. At least one of the inner walls of the cavity member 3 is provided with a first scale.

The endoscope 6 is slidably disposed in the inner tube in the axial direction of the outer tube 2 to acquire images of the prolapsed tissue corresponding to the first scale on the lumen 3, so that the axial dimension of the prolapsed tissue can be obtained.

The driving mechanism comprises a plurality of supporting rods 5 respectively corresponding to the cavity parts 3, an inner tube 4 slidably arranged in the outer tube 2 along the axial direction of the outer tube 2, a button 7 for driving the inner tube 4 to slide, and a lever 8 rotatably arranged in the outer shell 1 through a pivot 12. The number of the supporting rods 5 is six, and the supporting rods correspond to the six cavity pieces 3 one by one. Each stay 5 has opposite ends, one of which is rotatably connected to the cavity member 3 and the other of which is rotatably connected to the outer end of the inner tube 4, thereby constituting a slider-crank mechanism for driving the cavity member 3 to rotate through the inner tube 4. Wherein, the rotation connection of the stay bars 5, the cavity member 3 and the inner tube 4 is specifically pivoted, the other ends of the six stay bars 5 are specifically and respectively and rotatably connected with the outer end of the inner tube 4 through a second fixing ring 41, the second fixing ring 41 is fixedly sleeved on the distal end of the inner tube 4 along the circumferential direction of the inner tube 4, and the other ends of the stay bars 5 are rotatably sleeved on the second fixing ring 41; the button 7 is slidably arranged on the shell 1, the button 7 and the inner tube 4 are respectively positioned at two opposite sides (upper side and lower side in fig. 2) of the pivot 12, the proximal end of the button 7 is pivoted with one end of the lever 8, and the inner tube 4 is movably connected with the other end of the lever 8, so that the inner tube 4 can move rightwards along with the button 7; as shown in fig. 2, after the button 7 is pressed, the upper end of the lever 8 rotates rightward, thereby driving the inner tube 4 to move rightward and driving the cavity member 3 to open. From the sliding displacement of the push buttons 7, the angle at which the pocket members 3 open can be converted, thereby calculating the circumferential dimension of the prolapsed tissue located between the pocket members 3. In this embodiment, preferably, a second scale for indicating the sliding displacement of the button 7 is provided on the housing 1 and/or the button 7.

In this embodiment, each cavity member 3 includes a first segment 31 and a second segment 32, wherein a proximal end portion of the first segment 31 is rotatably connected to a distal end portion of the outer tube 2, and the second segment 32 extends from the distal end portion of the first segment 31 in a bending manner. A pre-tightening ring 33, such as a silica gel ring, with elasticity is sleeved outside the plurality of cavity members 3. Specifically, grooves are respectively formed on the outer walls of the connecting parts of the first section 31 and the second section 32 of each cavity member 3, and the pretightening rings 33 are clamped in the grooves.

For the connection between the button 7 and the housing 1, specifically, a chute 11 is formed on the housing 1, the chute 11 specifically extends along the axial direction of the outer tube 2, and the button 7 is slidably disposed in the chute 11. The drive mechanism further comprises a return spring 9 arranged between the inner tube 4 and the outer housing 1. The reset spring 9 is specifically a pressure spring, the pressure spring is sleeved on the inner tube 4, a bulge is arranged on the inner tube 4, one section of the reset spring 9 abuts against the shell 1, and the other end abuts against the bulge of the inner tube 4. When the push button 7 is released, the elastic restoring force of the restoring spring 9 drives the inner tube 4 to restore, the inner tube 4 moves proximally relative to the outer tube 2, and the cavity member 3 rotates inwards under the action of the stay 5 and the pre-tightening ring 33 to restore to the closed state. When the button 7 is pressed, the button 7 slides along the sliding groove 11 on the shell 1, the button 7 drives the lever 8, the lever 8 drives the inner tube 4 to move distally along the axial direction of the outer rod, the supporting rod 5 drives the cavity piece 3, and the cavity piece 3 rotates around the fixed ring and gradually expands. The six cavity pieces 3 form a cavity, relative scales are arranged between the button 7 and the shell 1, and the relative scales represent the opening size of the cavity pieces 3 at different positions. The endoscope 6 is moved axially along the outer tube 2 to observe the state and condition of the tissue accommodated in the cavity. The button 7 is released, the reset spring 9 drives the button 7 to reset, and the containing cavity is closed.

The rectal prolapse meter further includes a protective cover 61 fixedly provided in the inner tube 4, and the endoscope 6 is axially slidably provided in the protective cover 61 along the outer tube 2.

In the closed state, the plurality of cavity members 3 are relatively folded to be capable of entering the rectum; in the open state, the plurality of chamber elements 3 are relatively open, so that a chamber is formed between them, which allows prolapsed tissue to enter. It should also be noted that, since the outer tube 2, the inner tube 4, the protective cover 61 and the portions of the endoscope 6 and the cavity member 3 need to be introduced from the anal orifice into the rectum, the outer diameters of these members need to be small in the closed state, and in particular, the outer diameter of the junction of the first section 31 and the second section 32 of the cavity member 3 cannot be excessively large; in addition, in the closed state, each cavity member 3 is folded to the outer end thereof close to the protecting cover 61, and the plurality of cavity members 3 are integrally formed into a substantially conical structure to reduce resistance to entering the rectum.

The following describes in detail the working procedure for measuring rectal prolapse tissue using the rectal prolapse meter:

after entering the rectum through anus, the rectal prolapse measuring instrument is pushed down, the button 7 is pressed down, the inner tube 4 slides distally relative to the outer tube 2, the six cavity pieces 3 are all rotated outwards under the action of the supporting rod 5 to open and prop up the rectal wall, and the instrument is pushed to slide prolapse tissues into the cavity until the prolapse tissues in the cavity are not increased any more; the endoscope 6 enters the cavity to illuminate the cavity and the prolapsed tissue, and the tissue, the cavity, the positional relationship between the tissue and the cavity and the scale of the cavity piece 3 are observed through the endoscope 6, so that the axial size of the prolapsed tissue is read according to the first scale corresponding to the tissue; the sliding displacement of the button 7 is determined through the scales on the shell 1 and the button 7, so that the circumferential size of the sagging tissue is converted; namely, the prolapse amount is judged according to the opening size of the cavity part 3 and the depth of the prolapse tissue entering the cavity, so as to realize quantitative detection. After the measurement is finished, the button 7 is released, the prolapse measuring instrument is pulled out from the anus, and the measurement is finished.

The above-described embodiments are provided for illustrating the technical concept and features of the present invention, and are intended to be preferred embodiments for those skilled in the art to understand the present invention and implement the same according to the present invention, not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
