Description

TECHNICAL FIELD

[0001] The technical field of the fixed speculum device relates to the field of medical instruments, in particular to a device for fixing an anoscope or speculum on a speculum device, facilitating the treatment of anorectal surgery. BACKGROUND

[0002] In traditional anorectal surgery, there is no effective method to protect and expose the rectal mucosa, and the surgical field is poor, which can easily cause damage to the rectal mucosa, bleeding, and uneven suture in the same plane during surgery, increasing the risk of surgery and easily causing surgical failure, even secondary surgery.

[0003] Currently, the anoscope or speculum needs to be fixed on the patient's body before surgery, usually by suturing the patient's anal canal tissue with sutures. The nerve plexus around the anal canal is relatively dense, and suturing is particularly painful, causing great pain to the patient. It is more cumbersome for medical staff to suture, prolonging the operation time. After the operation, the anoscope or speculum needs to be removed, and the sutures need to be removed. The suture site is painful even after the anesthetic wears off, and the patient cannot sit down for a period of time. Therefore, it is necessary to provide a fixed anoscope or speculum device. SUMMARY

[0004] The purpose of the present application is to provide a fixed speculum device to overcome the above-mentioned deficiencies, which has an upper fixing ring, a lower fixing ring and a speculum passage pipe fixing belt. The fixed speculum device can be conveniently tied on the anus during surgery, and the anoscope or speculum is installed and fixed in the fixed speculum device. The anoscope or speculum does not move during surgery, and does not need to be held by the surgical operator, reducing the surgical operator's operation trouble, ensuring the success of the surgery, shortening the operation time and reducing the patient's pain.

[0005] A fixed speculum device is implemented by adopting the following technical solutions:

[0006] A fixed speculum device includes an upper fixing ring, a lower fixing ring and a fixing belt. The upper fixing ring and the lower fixing ring are connected by a speculum passage pipe. An anal canal pad positioning groove is provided between the upper fixing ring and the lower fixing ring to facilitate the installation of the fixed speculum device on the anal canal pad tissue during surgery. Two groups of fixing belts are mounted on the upper fixing ring to tie the patient's thighs during surgery, thereby fixing the fixed speculum device.

[0007] The speculum passage pipe is a trumpet-shaped passage pipe, and the bottom of the speculum passage pipe is provided with a speculum passage, which is a straight passage, facilitating the insertion of the anoscope or speculum into the anus and intestines.

[0008] A balloon can be fitted outside the speculum passage pipe between the upper fixing ring and the lower fixing ring. The height of the anal canal pad positioning groove can be adjusted according to the thickness L of the anal canal pad tissue. The balloon is provided with an inflation or water injection structure, which can be inflated or water injected.

[0009] The upper fixing ring has a diameter greater than the lower fixing ring.

[0010] The viewing sleeve channel tube is provided with a viewing sleeve channel in the middle, which is used to insert an anoscope or a viewing sleeve. The inner wall of the viewing sleeve channel tube is provided with a plurality of fixed viewing sleeve bosses. The fixed viewing sleeve bosses are elastic bosses, which are clamped on the anoscope or the fixed hole of the viewing sleeve during use, and are used to fix and position the anoscope or the viewing sleeve.

[0011] The viewing sleeve channel can be provided with an inner balloon, which can adjust the M diameter of the viewing sleeve channel according to the size of the inserted anoscope or viewing sleeve, so as to fix the anoscope or viewing sleeve. The balloon is provided with an inflation or water injection structure, which can be inflated or water injected.

[0012] The fixed viewing sleeve device is made of soft elastic material, which can be silicone, latex, polyethylene, or polypropylene, etc. The upper fixing ring, the lower fixing ring and the viewing sleeve channel tube can be integrally formed by injection molding.

[0013] By injection molding.

[0014] During surgery, the fixed viewing sleeve device is sleeved on the anal canal pad tissue through the anal canal pad positioning groove between the upper fixing ring and the lower fixing ring. The outer part of the viewing sleeve channel tube can be sleeved with a balloon, which can adjust the height of the anal canal pad positioning groove according to the thickness L of the anal canal pad tissue. Then, the two groups of fixing belts on the upper fixing ring are tied on the patient's thigh, and the fixed viewing sleeve device is fixed.

[0015] The anoscope or the viewing sleeve used in surgery is inserted into the viewing sleeve channel. The plurality of fixed viewing sleeve bosses provided on the inner wall of the viewing sleeve channel tube are clamped on the fixed hole of the anoscope or the viewing sleeve, and are used to fix and position the anoscope or the viewing sleeve. The viewing sleeve channel can be provided with an inner balloon, which can adjust the M diameter of the viewing sleeve channel according to the size of the inserted anoscope or viewing sleeve, so as to fix the anoscope or viewing sleeve.

[0016] The rectoscope in surgery can make the image of the lesion part of the patient most clearly displayed on the computer screen. The diameter of the mirror body is small, and the rectoscope can be conveniently inserted into the middle hole of the anoscope or the viewing sleeve installed and fixed in the fixed viewing sleeve device, enter the intestinal tract, and the lens can be checked and treated at multiple angles and multiple directions. Surgical instruments can also be conveniently inserted into the middle hole of the anoscope or the viewing sleeve installed and fixed in the fixed viewing sleeve device, enter the anus and intestines, and perform anus and intestine cutting and anastomosis surgery.

[0017] The fixed viewing sleeve device has reasonable design, compact structure and convenient use. The upper fixing ring, the lower fixing ring and the viewing sleeve passage pipe fixing belt are connected through the viewing sleeve passage pipe, the anus pad positioning groove is arranged between the upper fixing ring and the lower fixing ring, the fixed viewing sleeve device is sleeved on the anus pad tissue during the operation, two groups of fixing belts are arranged on the upper fixing ring and are used for being tied on the patient's thigh during the operation, and the fixed viewing sleeve device is fixed.

[0018] During the operation, the fixed viewing sleeve device can be conveniently tied on the anus, the anoscope or the viewing sleeve is installed and fixed in the fixed viewing sleeve device, the anoscope or the viewing sleeve does not move during the operation, and the operation personnel do not need to hold the anoscope or the viewing sleeve, so that the operation of the operation personnel is reduced, the operation time is reduced, and the operation success is ensured.

[0019] The anoscope or the viewing sleeve does not need to be sewn on the anus tissue of the patient by using a suture before the operation, and is directly arranged in the viewing sleeve passage of the fixed viewing sleeve device, so that the operation time is shortened, and the pain of the patient is reduced.

[0020] The fixed viewing sleeve device is made of soft elastic material, the soft elastic material can be silicone, latex, polyethylene or polypropylene, the upper fixing ring, the lower fixing ring and the viewing sleeve passage pipe can be integrally formed through injection molding, and the tying belt is arranged, so that the production cost is low.
