Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a genital examination sampler. Background Technique

[0002] Gynecology is a diagnostic and treatment subject in medical institutions, which is a professional department for diagnosing and treating female gynecological diseases. It is divided into Western medicine gynecology and traditional Chinese medicine gynecology. Gynecological diseases include diseases of the female reproductive system, including vulvar diseases, genital diseases, uterine diseases, fallopian tube diseases, ovarian diseases, etc. The female reproductive system mainly includes the genital organs, the uterus, and the ovaries. Among them, the genital organs and the uterus are very susceptible to diseases. For example, in the examination and treatment of the cervix, the sampling and examination of cervical biopsy specimens play an important role. Therefore, in cervical biopsy, sampling forceps are usually used to take biopsy specimens.

[0003] In cervical biopsy, usually the vagina is first dilated with a speculum to facilitate the doctor to observe the vaginal wall and the cervical morphology. Then the doctor holds the sampling forceps and inserts them into the vagina. The sampling forceps are used to cut and take the biopsy specimen, and then the sampling forceps are taken outwards to complete the sampling of the cervical biopsy specimen. However, during this process, due to improper operation angle or insufficient closing force of the sampling forceps, the sampling forceps may not be able to cut and separate the tissue after clamping the tissue. When taking out the sampling forceps outwards, it may cause traction injury due to tissue adhesion, resulting in local bleeding, mucosal tearing or increased pain of the patient, and may aggravate cervical injury. For this reason, we propose a genital examination sampler. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Example 1

[0038] Please refer to Figures 1 to 14 , the present invention provides a technical solution: a genital examination sampler, comprising: a fixed handle 11, a movable handle 12 is hingedly arranged on the fixed handle 11, an outer tube 13 is fixedly arranged on one side of the fixed handle 11, a lower clamp head 14 is fixedly arranged on one side of the outer tube 13, and an upper clamp head 15 is hingedly arranged on one side of the lower clamp head 14 through a hinge shaft.

[0039] It further comprises: a clamping component 2, the clamping component 2 is arranged inside the fixed handle 11, and the clamping component 2 is used for clamping living tissue;

[0040] An auxiliary component 3, the auxiliary component 3 is arranged on one side of the clamping component 2, and when the clamping component 2 fails to cut living tissue, the auxiliary component 3 assists the clamping component 2 to cut living tissue;

[0041] A self-locking component 4, the self-locking component 4 is arranged on one side of the fixed handle 11, and when the clamping component 2 fails to cut living tissue for multiple times, the self-locking component 4 automatically locks the fixed handle 11 and the movable handle 12;

[0042] A support component 5, the support component 5 is arranged outside the outer tube 13, and the support component 5 is used for supporting and guiding the sampling forceps during use.

[0043] A reed is arranged between the fixed handle 11 and the movable handle 12. By holding the movable handle 12 and rotating it close to the fixed handle 11, and through the clamping component 2, the upper clamping head 15 is driven to rotate close to the lower clamping head 14. The upper clamping head 15 and the lower clamping head 14 are used to cut the cervical living tissue. When the upper clamping head 15 and the lower clamping head 14 fail to cut and separate the living tissue through the clamping component 2, through the auxiliary component 3, it can assist the clamping component 2 to cut the living tissue, automatically increase the closing force between the upper clamping head 15 and the lower clamping head 14, so as to cut and separate the living tissue, and prevent traction damage caused by tissue adhesion. When the clamping component 2 fails to cut and separate the living tissue, the self-locking component 4 will record. When the number of times recorded by the self-locking component 4 reaches the set number of times, it will automatically lock and fix the fixed handle 11 and the movable handle 12, so that the doctor can no longer hold the movable handle 12 and rotate it close to the fixed handle 11. At this time, the doctor needs to check the sampling forceps and check whether the cutting edges of the upper clamping head 15 and the lower clamping head 14 are blunt, and whether it is due to the improper closing of the sampling forceps itself that the living tissue cannot be cut and separated. That is, when the clamping component 2 fails to cut the living tissue multiple times, it may not be an operation problem of the doctor using the sampling forceps due to insufficient closing force, but a problem of the sampling forceps itself; through the support component 5, it can be used in cooperation with the speculum 6 to support and guide the sampling forceps during use, so that it is convenient for the doctor to adjust to the appropriate operation angle and cutting angle when cutting the living tissue, and can maintain the appropriate support position to further ensure the cutting of the living tissue.

[0044] The clamping component 2 includes a sleeve rod 21 hinged to the movable handle 12 through a hinge shaft. A push rod member 22 is slidably arranged in the sleeve rod 21. The push rod member 22 passes through the inside of the outer tube 13. Activity grooves 29 are symmetrically arranged inside the upper clamping head 15. The activity grooves 29 are adapted to one end of the push rod member 22 close to the upper clamping head 15. One end of the push rod member 22 close to the upper clamping head 15 is movably arranged along the activity grooves 29, so that when the push rod member 22 pushes the upper clamping head 15 to move, the upper clamping head 15 can be rotated downward close to or upward away from the lower clamping head 14; A first spring 23 fixedly arranged on the inner side of the sleeve rod 21 is fixedly arranged on one side of the push rod member 22. An installation shell 25 is fixedly arranged on the lower side of the sleeve rod 21. A first electromagnetic block 26 is fixedly arranged inside the installation shell 25. A plug rod member 27 adsorbed to the first electromagnetic block 26 is slidably arranged inside the installation shell 25. The plug rod member 27 movably penetrates through the lower side of the sleeve rod 21. A second spring 28 fixedly arranged with the plug rod member 27 is fixedly arranged on the lower side of the sleeve rod 21. A jack adapted to the upper side of the plug rod member 27 is arranged on the lower side of the push rod member 22. Initially, the upper end of the plug rod member 27 is inserted into the jack to limit and fix the push rod member 22 and the sleeve rod 21; A camera module 24 is installed on the outer tube 13. The camera module 24 is located on one side close to the upper clamping head 15. Through the camera module 24, the doctor can easily observe the position of the living tissue during clamping, which is convenient for cutting the living tissue.

[0045] By holding the movable handle 12 and rotating it close to the fixed handle 11, the sleeve rod 21 can be pushed to move close to the outer tube 13, and the push rod member 22 is driven to move synchronously, so as to drive the upper clamp head 15 to rotate downward close to the lower clamp head 14, and the living tissue is cut by the upper clamp head 15 and the lower clamp head 14.

[0046] The auxiliary component 3 includes a first connecting member 31 fixedly arranged with the push rod member 22. A rotating member 32 is movably arranged on the lower side of the first connecting member 31. A second connecting member 34 is movably arranged on the lower side of the rotating member 32. The rotating member 32 is provided with movable through grooves at the positions of the first connecting member 31 and the second connecting member 34. The first connecting member 31 and the second connecting member 34 are respectively movably arranged with the rotating member 32 through the movable through grooves on both sides of the rotating member 32. A support column 33 fixedly arranged with the fixed handle 11 is rotatably arranged on the rotating member 32. The support column 33 is located on the side close to the first connecting member 31. When the adsorption block 35 is adsorbed by the second electromagnetic block 36, the push rod member 22 and the upper clamp head 15 are driven, so that when cutting, the upper clamp head 15 and the lower clamp head 14 are closed more tightly, or when increasing the closing force between the upper clamp head 15 and the lower clamp head 14, through the lever principle of the rotating member 32, it is more convenient to drive the push rod member 22 and the upper clamp head 15; A second connecting member 34 is fixedly arranged with an adsorption block 35 slidably arranged with the fixed handle 11 on the lower side. A limiting groove 37 adapted to the adsorption block 35 is arranged inside the fixed handle 11. The adsorption block 35 is slidably arranged along the limiting groove 37;

[0047] A second electromagnetic block 36 is fixedly arranged on one side of the fixed handle 11 where the adsorption block 35 is located. After being energized, the second electromagnetic block 36 adsorbs the adsorption block 35. A pressure sensor 38 is installed on the upper clamp head 15. A control board 39 is arranged on one side of the fixed handle 11. Control elements are installed inside the control board 39. A first switch 310 is installed on one side of the control board 39;

[0048] When the living tissue is clamped by holding the movable handle 12 and rotating it close to the fixed handle 11, the movement of the push rod 22 will drive the movement of the first connecting member 31, first rotating the upper side of the rotating member 32 toward the outer tube 13 by a certain amplitude, so that the lower side of the rotating member 32 drives the second connecting member 34 and the adsorption block 35 to move a certain distance close to the second electromagnetic block 36. When the upper clamp head 15 and the lower clamp head 14 fail to cut and separate the living tissue through the clamping assembly 2, the living tissue will be pulled due to tissue adhesion, which will conflict with the pressure sensor 38. That is, when the pressure sensor 38 detects pressure, indicating that the living tissue cannot be cut and separated, the first electromagnetic block 26 will be controlled to be energized to produce an adsorption effect on the plug rod 27, so that the plug rod 27 moves downward out of the insertion hole on the lower side of the push rod 22, the second spring 28 stretches, and controls the second electromagnetic block 36 to be energized to produce an adsorption effect on the plug rod 27. The adsorption effect of the attachment block 35 causes the adsorption block 35 and the second connecting member 34 to move close to the second electromagnetic block 36, and through the rotating member 32, the first connecting member 31 and the push rod member 22 are pushed close to the upper clamp head 15, and the first spring 23 is extended, thereby continuing to drive the upper clamp head 15 to rotate downward to cut the living tissue, so that the upper clamp head 15 and the lower clamp head 14 are closed more tightly during cutting, or the adsorption effect of the second electromagnetic block 36 on the adsorption block 35 can increase the closing force between the upper clamp head 15 and the lower clamp head 14, thereby assisting in cutting and separating the living tissue and preventing traction damage caused by tissue adhesion. After the living tissue is taken out, the first switch 310 can be pressed to de-energize the first electromagnetic block 26 and the second electromagnetic block 36, and under the elastic force of the second spring 28 and the first spring 23, the insertion rod member 27 is reinserted into the jack on the lower side of the push rod member 22.

[0049] The self-locking assembly 4 includes a connection shell 41 fixedly arranged with the fixed handle 11. A third electromagnetic block 414 is fixedly arranged inside the connection shell 41. A first shell 42 adsorbed to the third electromagnetic block 414 is slidably arranged inside the connection shell 41. A first guide groove 45 adapted to the first shell 42 is arranged inside the connection shell 41. The first shell 42 is slidably arranged along the first guide groove 45. A sixth spring 413 fixedly arranged with the inner side of the connection shell 41 is fixedly arranged on one side of the first shell 42. A second shell 44 is fixedly arranged inside the connection shell 41. Limiting tooth blocks 410 are slidably arranged inside both the first shell 42 and the second shell 44. Pulling rods 411 are fixedly arranged on one side of the two limiting tooth blocks 410 away from each other. The pulling rod 411 inside the first shell 42 movably penetrates the first shell 42 and one side of the connection shell 41 and can be slidably arranged along the movable penetration part of the connection shell 41. The pulling rod 411 inside the second shell 44 movably penetrates the second shell 44 and one side of the connection shell 41. Fifth springs 412 sleeved on the outer sides of the pulling rods 411 are fixedly arranged on one side of the two limiting tooth blocks 410. One end of the fifth spring 412 inside the first shell 42 away from the limiting tooth block 410 is fixed to the inner side of the first shell 42. One end of the fifth spring 412 inside the second shell 44 away from the limiting tooth block 410 is fixed to the inner side of the second shell 44;

[0050] A helical tooth block 43 slidably arranged with the connection shell 41 is arranged between the two limiting tooth blocks 410. The helical tooth block 43 cooperates with the limiting tooth blocks 410 on both sides. A second guide groove 46 adapted to the helical tooth block 43 is arranged inside the connection shell 41. The helical tooth block 43 is slidably arranged along the second guide groove 46. A fourth spring 49 fixedly arranged with the inner side of the connection shell 41 is fixedly arranged on one side of the helical tooth block 43. A limiting column 47 is slidably arranged on the other side of the helical tooth block 43. A limiting protrusion is arranged inside the limiting column 47, which can play a role in limiting and guiding the limiting column 47. A third spring 48 fixedly arranged with the helical tooth block 43 is fixedly arranged inside the limiting column 47. A through hole 415 adapted to the limiting column 47 is arranged through one side of the fixed handle 11. A limiting hole 416 adapted to the limiting column 47 is arranged on one side of the movable handle 12;

[0051] When it is impossible to cut and separate the living tissue, when the second electromagnet 36 is controlled to be energized by the pressure sensor 38, the third electromagnet 414 can be controlled to be energized simultaneously to generate an adsorption effect on the first housing 42, so that the first housing 42 moves close to the third electromagnet 414 along the first guide groove 45, and the sixth spring 413 elongates. When the first housing 42 moves to the other end of the first guide groove 45, the first housing 42 stops moving. The movement of the first housing 42 can drive the limit tooth block 410 inside it to move synchronously. Through the engagement of the first housing 42 and the helical tooth block 43, the helical tooth block 43 can be driven to move the same distance close to the fixed handle 11, and the fourth spring 49 elongates. At the end of this cutting, when the first switch 310 is pressed, the third electromagnet 414 can be controlled to be powered off simultaneously. Under the elastic force of the sixth spring 413, the first housing 42 is driven to move reversely and reset. And through the limiting effect of the limit tooth block 410 in the second housing 44 on the helical tooth block 43, the reverse movement of the helical tooth block 43 can be blocked. In this way, every time the living tissue fails to be cut and separated, the helical tooth block 43 can be made to move a certain distance close to the fixed handle 11, so that the number of times the living tissue fails to be cut and separated can be converted into the distance that the helical tooth block 43 moves close to the fixed handle 11 for recording. When the living tissue fails to be cut and separated many times, the movement of the helical tooth block 43 will drive the limit post 47 through the through hole 415, and under the action of the third spring 48, the limit post 47 abuts against one side of the movable handle 12. After the movable handle 12 is reset, under the elastic force of the third spring 48, the limit post 47 is inserted into the limit hole 416, so as to limit the movable handle 12 from rotating again, lock and fix the fixed handle 11 and the movable handle 12, so that the doctor cannot hold the movable handle 12 and rotate it close to the fixed handle 11. At this time, the doctor needs to check the sampling forceps and check whether the cutting edges of the upper jaw 15 and the lower jaw 14 are blunt, and whether it is due to the improper closing of the sampling forceps itself that the living tissue cannot be cut and separated, that is, when the clamping component 2 fails to cut the living tissue many times, it may not be an operation problem of the doctor using the sampling forceps due to insufficient closing force, but may be a problem of the sampling forceps itself. When the self-locking component 4 locks the movable handle 12, the number of times the sampling forceps fails to cut the living tissue is preferably three times;

[0052] After checking the relevant situation, by simultaneously pushing the two pull rods 411 outward, the two limit tooth blocks 410 can be disengaged from the helical tooth block 43. Under the elastic force of the fourth spring 49, the helical tooth block 43 moves reversely and resets, and the limit post 47 resets, releasing the lock on the movable handle 12.

During cervical biopsy, the vagina can be dilated through the speculum 6, so that the doctor can cut the living tissue through the biopsy forceps. The support rod member 56 can be fastened to the fixing member 57 by screws, and the speculum 6 and the support assembly 5 are used to assist in supporting and guiding the biopsy forceps.

[0056] A screw rod 59 is rotatably provided on one side of the support block 51. A clamping member 511 is threadedly provided on the upper side of the screw rod 59. A limiting rod 510 fixedly provided with the support block 51 penetrates and slides through one side of the clamping member 511. The inner sides of the clamping member 511 and the support block 51 are set to be arc-shaped adapted to the outer tube 13. Ball beads 512 are evenly and movably provided on the inner sides of the arc-shaped clamping member 511 and the support block 51. After the outer tube 13 is clamped by the clamping member 511 and the support block 51, the ball beads 512 abut against the outer side of the outer tube 13. Fixed shells 513 are fixedly provided on one side of each of the two slide sleeves 55. A fourth electromagnetic block 514 is fixedly provided in the fixed shell 513. A second switch 516 is installed on one side of the installation member 53. The control element can be arranged in the installation member 53. A toothed block 515 adsorbed to the fourth electromagnetic block 514 is slidably provided in the fixed shell 513. The toothed block 515 movably penetrates through the fixed shell 513 and one side of the slide sleeve 55. The toothed block 515 cooperates with the rack bar 54. Seventh springs 58 fixedly provided with the fixed shell 513 are symmetrically fixedly provided on one side of the toothed block 515.

[0057] In use, the outer tube 13 can be inserted into the clamping member 511 and the support block 51 from the side end. By rotating the screw 59, the clamping member 511 moves downward along the limiting rod 510 to clamp the outer tube 13 between the support block 51 and the clamping member 511. When inserting or removing the sampling forceps, the outer tube 13 moves along the ball 512 on the inner arc of the clamping member 511 and the support block 51, and the ball 512 rolls. Thus, through the arrangement of the ball 512, the flexibility of the sampling forceps when moving inward or outward can be ensured. The support block 51 can be adjusted in multiple directions and angles through the support member 52, enabling the sampling forceps to be flexibly adjusted at multiple angles. When the sampling forceps move in the up-down or left-right directions, the second switch 516 can be pressed to control the fourth electromagnet 514 to be energized to generate an adsorption effect on the toothed block 515, causing the toothed block 515 to disengage from the toothed rod 54 and releasing the limiting effect on the toothed rod 54. The seventh spring 58 is compressed. Thus, when the sampling forceps are adjusted in the up-down or left-right directions, the sliding sleeve 55 and the support rod member 56 can rotate, and the toothed rod 54 slides along the sliding sleeve 55. Thereby, the flexibility of the operation angle adjustment when the sampling forceps cut the living tissue can be ensured, facilitating the doctor to adjust the sampling forceps to the appropriate operation angle and cutting angle when cutting the living tissue. Then, the second switch 516 can be pressed again to cut off the power supply of the fourth electromagnet 514. Under the elastic force of the seventh spring 58, the toothed block 515 is engaged with the toothed rod 54. Thus, through the limiting effect of the two toothed blocks 515 on the toothed rod 54, that is, restricting the sliding of the toothed rod 54 along the sliding sleeve 55, the support position where the sampling forceps are located at this time can be maintained, improving the stability when the doctor cuts the living tissue and facilitating the adjustment to the appropriate operation angle and cutting angle. Thereby, the cutting of the living tissue can be further ensured.
