Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a drainage guide for high-position anal fistula and deep abscess. Background Art

[0002] Anorectal surgery is a common disease specialty in clinical departments, and the incidence of patients is extremely high. There is a saying that "nine out of ten men have hemorrhoids, and ten out of ten women have hemorrhoids". In particular, deep abscesses and high anal fistulas are the most serious and difficult to cure diseases in anorectal surgery, with a very high recurrence rate. The main reason for recurrence is that the infection site is deep in the rectum, sometimes exceeding the rectal ring or reaching the space behind the rectum, subperitoneal. From 3 o'clock and 9 o'clock as the center, upward or downward.

[0003] Our existing surgical instruments for exploring the abscess cavity are mostly 16cm or 18cm tissue clamps. Due to the special anatomical structure of the anal canal, which is composed of numerous cavities and weak muscle groups, traditional tissue clamps for exploring cavities and using fingers to open the intervals between cavities cause great trauma to muscles, nerves, and blood vessels. If deep large blood vessels are injured by clamping, deep bleeding will occur, which is difficult to stop.

[0004] The most critical problem is that it is difficult to lower the drainage strip to the bottom of each cavity because the tissue forceps cannot be bent and deep drainage cannot be inserted, which can directly lead to surgical failure. Traditional probes are not long enough, are easily deformed, and cannot bend back in the deep part, resulting in some patients undergoing five or six surgeries but still ending in failure.

[0005] Therefore, there is a need for a guide that can be made in large, medium or small sizes according to the shape of the buttocks and can be suitable for obese patients weighing more than 100 or 200 pounds. Summary of the invention

[0006] In order to solve the problems of the prior art, the present invention provides a drainage guide for high anal fistula and deep abscess.

[0007] In order to solve the above technical problems, the present invention is realized by the following technical scheme: a high-position anal fistula and deep abscess drainage guide, comprising a guide body, the guide body is composed of a guide head and a guide tail,

[0008] The guide head is configured as a long smooth column, one end of which is provided with a curved connecting section for smooth connection with one end of the guide tail;

[0009] The tail of the introducer is set in a smooth arc shape, which is made according to the shape of the patient's buttocks and body shape. A needle is set at one end, and at least one needle eye is set inside the needle for inserting and fixing the silk thread or rubber strip for drainage;

[0010] The guide head and the guide tail are integrally made of hard material.

[0011] In this implementation, the specific operation process is as follows:

[0012] Handle part:

[0013] Graduations can be drawn on the handle, and the length is generally 10-12 cm or 12-15 cm.

[0014] The scale design takes into account the differences in patients' physical constitutions; 12cm is usually sufficient, and 15cm can be reached for particularly obese people.

[0015] Arc part:

[0016] An opening distance (between 11 and 21) of 12 cm can meet general usage needs.

[0017] The radius of the arc is designed to be 12 cm.

[0018] Usage scenarios

[0019] It is mainly used for the treatment of deep abscesses or renal anal fistulas.

[0020] Abscess and anal fistula are different stages of the same disease, and the surgical methods are basically the same, both requiring reaching the bottom of the lesion cavity.

[0021] How to use

[0022] Preoperative preparation:

[0023] After the abscess is opened, the depth and direction of the cavity are explored.

[0024] According to the patient's position (such as stone position), determine the location of the abscess (such as 3 o'clock or 9 o'clock).

[0025] Bootloader Operation:

[0026] Taking the 3-point abscess as an example, hold the guide in the right hand and press the anus with the middle finger of the left hand (because the index finger may not be long enough).

[0027] When lowering the guide with the right hand, the left hand can feel the shoulder of the guide to ensure that the intestinal wall is not cut.

[0028] Rotate the guide along the bottom edge of the cavity to find the appropriate point (such as the 6 o'clock position).

[0029] Keep your left hand on the anus and use your right hand to push the guide out.

[0030] Subsequent operations:

[0031] Place number one wire in the tip hole of the guide.

[0032] Lower the strip and secure it to the guide, then bring the strip back into the cavity.

[0033] Pull out the guide and keep the adhesive strip for subsequent processing.

[0034] Contralateral surgery:

[0035] When performing surgery on the other side (such as the 9 o'clock position), the operation is reversed.

[0036] Precautions

[0037] The intestinal wall is very thin, so be gentle when operating to avoid scratching the intestinal wall.

[0038] The scale design takes into account the differences in patient physiques and ensures that the introducer can reach the required depth.

[0039] Pay attention to hygiene and safety during use to avoid cross infection.

[0040] The specific functions are:

[0041] Precise positioning: The drainage guide for high-position anal fistula and deep abscess can accurately locate the position of anal fistula or abscess through its unique head and tail design, improving the accuracy and safety of the operation.

[0042] Reduce damage: The head of the guide is set to be a long, smooth column with a curved connecting section, which can reduce damage to surrounding tissues and reduce surgical risks and complications.

[0043] Fixed drainage: The needle eye inside the needle can easily insert and fix the drainage thread or rubber strip to ensure the stability of the drainage tube and avoid displacement or falling off.

[0044] Improve surgical efficiency: The use of the guide simplifies the surgical process, improves surgical efficiency, shortens the operation time, and alleviates the patient's pain.

[0045] Promote recovery: Through precise drainage and proper postoperative treatment, wound healing can be promoted, the risk of infection can be reduced, and the patient's recovery process can be accelerated.

[0046] In a specific embodiment, the guide body is made of 304 stainless steel, the cross-sectional diameter is set to 4-5 mm, and is manually polished, drilled, and shaped.

[0047] In a specific embodiment, the surface of the introducer body is also provided with scale marks to facilitate the doctor to accurately judge the insertion depth of the introducer during the operation, thereby accurately locating the position of the anal fistula or abscess.

[0048] In a specific embodiment, the introducer body is provided with a variety of sizes to accommodate patients of different physiques.

[0049] The beneficial effects of the present invention are:

[0050] 1. The introducer head of the present invention adopts a long smooth columnar design with a curved connecting section, so that it can smoothly adapt to the internal environment during the insertion process, reducing friction and damage to surrounding tissues. The precise design of the needle and the needle eye enables the doctor to accurately locate the position of the anal fistula or abscess and perform effective drainage, avoiding tissue damage that may be caused by inaccurate positioning in traditional surgery;

[0051] 2. The guide is made of an integrated hard material, which ensures that it is not easy to deform or break during use, and improves the stability and safety of the operation. There is at least one needle eye inside the needle, which is convenient for inserting and fixing the drainage thread or rubber strip, simplifying the surgical steps, shortening the operation time, and reducing the surgical risk;

[0052] 3. Accurate drainage and proper postoperative treatment help reduce the risk of infection, promote wound healing, and accelerate the patient's recovery process. The design of the guide takes into account the patient's comfort and surgical effect, allowing patients to return to normal life and work faster after surgery.

[0053] 4. The design of the guide is ergonomic, making it easier for doctors to operate during surgery, reducing the difficulty and physical exertion of the surgery. The smooth connection between the needle and the tail of the guide, as well as the precise setting of the needle eye, make it easier for doctors to insert and fix the drainage material, improving the efficiency of the surgery.

[0058] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0059] like Figures 1 to 3The drainage guide for high-position anal fistula and deep abscess shown in the figure comprises a guide body, which is composed of a guide head 1 and a guide tail 2. The guide head 1 is arranged in a long and smooth columnar shape, and a curved connecting section 11 is arranged at one end thereof for smooth connection with one end of the guide tail 2; the guide tail 2 is arranged in a smooth arc shape, and is made according to the shape of the patient's buttocks and body shape, and a needle 21 is arranged at one end thereof, and at least one needle eye 211 is arranged inside the needle 21 for inserting and fixing the silk thread or rubber strip for drainage; the guide head 1 and the guide tail 2 are integrally made of hard material.

[0060] The guide body is made of 304 stainless steel, with a cross-sectional diameter set to 4-5mm, and is manually polished, drilled, and shaped.

[0061] The surface of the introducer body is also provided with scale marks to facilitate the doctor to accurately judge the insertion depth of the introducer during the operation, thereby accurately locating the position of the anal fistula or abscess.

[0062] Example: The patient had a deep abscess in the ischiorectal fossa (6-3-12 o'clock)

[0063] Operation record: After sacral anesthesia takes effect, routine sterile towels are laid and local disinfection is performed. The first transverse incision is made at 3 o'clock where the abscess is obviously raised (the length of the incision is greater than the predicted depth) to drain several milliliters of pus and expand the tissue at the edge of the incision. The fingers are inserted into the cavity, the necrotic tissue is peeled and scraped off, the abscess cavity interval is fully opened, the bottom is touched, and the size and direction of the cavity are sensed. The abscess cavity is measured to be a lateral T-shaped, with a vertical distance of about 9cm. The sacral extension direction of about 2cm at 12 o'clock is not the main channel, so there is no need for port-to-port drainage. The lateral distance extending to the 6 o'clock direction is about 5cm, which is the main channel, so port-to-port drainage is performed at 3-6 o'clock.

[0064] The method is as follows: insert the middle finger of the left hand into the anus, touch the straight anal ring for sensing and guiding, hold the right hand to the opposite drainage device, first probe the tip into the bottom of the cavity, feel with the left hand, find the right hand to find the angle, guide the head of the opposite drainage device to the 6 o'clock position in the direction of the cavity bottom, penetrate the entire cavity, extend the arc from 3 to 6 o'clock to 3 cm from the anal edge, fix with the right hand, remove with the left hand, make the outlet at the skin bulge in front of the guide, expose the round hole at the front end of the guide, insert the fixed rubber strip with No. 1 silk thread, return to the original direction to bring in the drainage strip, and fix the two ends of the drainage strip. The operation is over.

[0065] In summary, the drainage guide for high-position anal fistula and deep abscess in this embodiment can significantly improve the accuracy and safety of the operation and promote the patient's recovery during the actual operation.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
