Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a surgical film for transperineal prostate biopsy. Background Art

[0002] Prostate biopsy is the most reliable examination for diagnosing prostate cancer. Transperineal prostate biopsy is recommended as the preferred surgical procedure by domestic and foreign guidelines due to its advantages such as low infection rate, simple preoperative preparation, and few postoperative complications. It is performed by inserting a B-ultrasound probe deep into the patient's rectum, and then under the real-time guidance and positioning of the transrectal B-ultrasound probe, the doctor inserts a puncture needle through the perineal skin into the prostate tissue to obtain a prostate tissue sample for pathological examination to determine the nature, type, and degree of prostate lesions, which is the gold standard for diagnosing prostate cancer.

[0003] Since transperineal prostate biopsy needs to be performed in the lithotomy position, and the puncture point is located below the scrotum, the hanging penis and scrotum of the patient in the lithotomy position are likely to block the puncture point, causing inconvenience to the operation. Therefore, the scrotum and penis need to be lifted during the operation. Since the puncture needle insertion point is close to the anus, when the B-ultrasound probe enters and exits the patient's rectum, the dirt and bacteria in the rectum are likely to splash out and contaminate the surgical field, easily leading to intraoperative or postoperative infection. Therefore, it is necessary to isolate the surgical site, block the rectum and the surgical puncture point to avoid mutual contact and prevent infection. At the same time, it is also necessary to prevent the B-ultrasound probe from directly contacting the patient's excrement and being contaminated. Since the tissue specimens obtained by prostate biopsy are small and few, the tissue is likely to fall, be lost, or be contaminated if not carefully scraped and transferred. Therefore, a more convenient and reliable specimen scraping and collection device is needed. In addition, in order to make the puncture needle visible in the B-ultrasound image, it is required that the needle insertion plane and the B-ultrasound probe plane remain the same at all times during prostate puncture, which is very difficult for doctors with insufficient experience. Therefore, a more convenient device is needed to guide the puncture needle. The existing surgical films have a simple structure and have many defects in the process of transperineal prostate biopsy.

[0004] Based on this, the present invention designs a surgical film for transperineal prostate biopsy to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a surgical film for perineal prostate puncture. This device is provided with a protective film with adhesiveness, which can avoid the excrement splashed from the rectum from contaminating the surgical field. At the same time, a B-ultrasound probe sheath integrated with the protective film is added, which can block the probe from the pollutants in the rectum, effectively avoiding cross-infection. An accommodation bag for holding up the scrotum and penis is added, which is convenient for doctors to expose the surgical field and operate during the operation. An angle scale for guiding the rotation direction of the probe and the puncture point of the puncture needle is also added, so that doctors can view the puncture needle path in real time in the B-ultrasound image, thereby achieving accurate puncture and avoiding damage to other tissues and organs. Moreover, this device is connected with a sampling piece, and after the puncture is completed, the sample at the tip of the puncture needle can be directly and conveniently removed, without the need to scrape and transfer with other instruments, avoiding sample loss and contamination during the transfer process, and at the same time shortening the operation time.

[0006] The present invention is implemented as follows: A surgical film for perineal prostate puncture, comprising:

[0007] A protective film, a sheath, a sampling piece and an angle scale;

[0008] The protective film is a square transparent film, and an avoidance groove is provided on each of the left and right side edges of the protective film. The avoidance groove is an inwardly concave circular arc groove;

[0009] An accommodation bag is also provided at the center of the protective film. The accommodation bag is a complete pocket with a straight rod at the upper end and a circular shape at the lower end. The edge of the accommodation bag is hermetically connected to the protective film to form an integral structure;

[0010] The back surface of the protective film is covered with an adhesive sheet, and the adhesive sheet does not cover the accommodation bag;

[0011] The sheath is a straight cylinder with an open front end. The sheath is connected to the bottom of the protective film, and the rear end of the sheath is closed;

[0012] The sampling piece is a square sheet-like film. A plurality of the sampling pieces are sequentially connected in the left-right direction to form a tear strip. The tear strip has a long strip structure, and a perforated line is provided between adjacent sampling pieces. The sampling pieces are connected through the perforated line;

[0013] An angle scale is also provided at the bottom of the front surface of the protective film. The center of the angle scale is the center of the sheath.

[0014] Further, the protective film is a transparent PVC film with a thickness not exceeding 0.2 mm.

[0015] Further, the sheath is a closed sleeve made of transparent PVC film;

[0016] An elastic ring is also sleeved on the outer wall of the open front end of the sheath. The elastic ring is a circular rubber band;

[0017] An anti-splash sheet is also connected to the outside of the sheath. The anti-splash sheet is also made of PVC film. The anti-splash sheet is a sheet-like structure that is annularly arranged on the outer wall of the sheath. The sheath is fixedly connected to the bottom edge of the protective film. The anti-splash sheet and the protective film are an integral structure. The annular width d of the anti-splash sheet is 5 cm;

[0018] The sheath is connected and fixed to the protective film through the anti-splash sheet.

[0019] Furthermore, the angle scale is an angular marking line in the shape of a protractor. The bottom straight edge of the angle scale overlaps with the bottom edge of the protective film;

[0020] The center of the angle scale is on the axis of the sheath, and the axis of the sheath is perpendicular to the plane where the protective film is located.

[0021] Furthermore, the back of the placement bag is covered with cotton cloth.

[0022] The beneficial effects of the present invention are as follows: 1. The present invention is a protective film, and an adhesive sheet is provided on the back of the protective film, so that the entire protective film can be pasted onto the patient's skin to protect the patient. Especially, it blocks the prostate puncture site from other easily contaminated parts such as the anus, effectively avoiding the direct contamination of the puncture wound by the dirt and bacteria in the rectum, preventing intraoperative and postoperative infections. Moreover, multiple sampling pieces are provided at the top of the protective film. After the puncture is completed, the sample at the tip of the puncture needle can be directly and conveniently placed on the sampling piece, without the need to scrape and transfer with other instruments, avoiding sample loss during the transfer process, reducing the operation time at the same time, and the easy-to-tear design enables the tissue sample to be torn off together with the sampling piece and immersed in the specimen fixing solution, and the sample always adheres to the sampling piece, which is convenient for subsequent pathologists to search for and extract the sample;

[0023] 2. The device is provided with a placement bag for lifting the scrotum and penis, which can restrict the patient's scrotum and penis, preventing them from blocking the surgical field and avoiding accidental injury to the testis and penis by the puncture needle. Moreover, the back of the placement bag is provided with opaque cotton cloth, which not only improves the comfort of the patient but also avoids the discomfort caused by the exposure of the patient's private organs;

[0024] 3. The sheath and the protective film are integrated through the anti-splash sheet, which can not only protect the B-ultrasound probe inserted into the rectum from feces and bacteria contamination, preventing cross-infection during subsequent repeated use of the probe, but also block the feces, bacteria and other pollutants splashed during the puncture process through the anti-splash sheet, avoiding contamination of the surgeon's sterile gloves and puncture needle;

[0025] 4. The device also adds an angle scale for guiding the rotation azimuth of the probe and the puncture point of the puncture needle. By inserting the puncture needle along the scale line at the same angle as the probe plane, the operator can view the puncture needle path in real time in the B-ultrasound image, thereby achieving precise puncture and avoiding accidental injury to the surrounding tissue organs of the prostate such as the bladder, urethra, and rectum during the operation, so as to reduce the occurrence of complications such as postoperative hematuria, bloody stools, and dysuria.

[0030] In the drawings, the list of components represented by each reference numeral is as follows:

[0031] 1 - protective film, 11 - placement bag, 12 - avoidance groove, 13 - adhesive film, 2 - sheath, 21 - elastic ring, 22 - splash-proof piece, 3 - sampling piece, 31 - perforated line, 4 - angle scale. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Please refer to Figures 1 to 3 shown. The present invention provides a surgical film for perineal prostate puncture. In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0033] In a specific embodiment of the technical solution of the present invention:

[0034] It includes a protective film 1, a sheath 2, a sampling piece 3 and an angle scale 4;

[0035] The protective film 1 is a square transparent PVC film with a thickness not exceeding 0.2 mm. It not only plays a blocking role but also, due to its thinness, facilitates the entry and exit of the puncture needle. Moreover, the transparent design does not obstruct the line of sight, helping to fully expose the surgical field. Before use, this device is folded and stored in a sterile bag, and is torn open for use after preoperative disinfection and draping are completed. The back of the protective film 1 is covered with an adhesive film 13. The back of the adhesive film 13 is covered with a release paper, which is used to protect the adhesive film 13 before pasting to keep it sticky. When in use, first tear off the release paper, and then paste the protective film 1 covered with the adhesive film 13 on the perineal skin of the patient. Due to its good elasticity and flexibility, it can be bent and deformed to fit well with the human skin. On each of the left and right side edges of the protective film 1, there is a relief groove 12, and the relief groove 12 is an inwardly concave circular arc groove, which just fits well and seals with the inner thigh arc when the patient is in the lithotomy position.

[0036] At the center of the protective film 1, there is also a placement bag 11. The placement bag 11 is a complete pocket with a straight rod at the upper end and a circle at the lower end. The edge of the placement bag 11 is sealed and connected to the protective film 1 as an integral structure. When in use, place the patient's penis in the straight rod bag at the upper end and the scrotum in the circular bag at the lower end, so as to hold up and limit the swinging of the scrotum and penis, avoiding blocking the surgical field and being accidentally injured during the operation. The back of the placement bag 11 is covered with cotton cloth, which can make the fitting part of the patient more comfortable and also block the scrotum and penis, avoiding the patient's embarrassment or psychological discomfort due to the exposure of private organs.

[0037] The back of the protective film 1 is covered with an adhesive film 13, and the adhesive film 13 does not cover the placement bag 11. The placement bag 11 has no adhesiveness to avoid causing discomfort to the patient by sticking to the scrotum and penis. The outer edge of the protective film 1 does not cover the adhesive film 13, forming an edge without adhesive, which is convenient for the doctor to tear off the protective film 1 from the patient by hand after the operation is completed.

[0038] The sheath 2 is a straight tube with an open front end. The sheath 2 is connected to the bottom of the protective film 1, and the rear end of the sheath 2 is closed.

[0039] The rear end of the sheath 2 is a closed elastic rubber transparent sleeve.

[0040] On the outer wall of the open front end of the sheath 2, there is also a elastic ring 21 sleeved. The elastic ring 21 is a circular rubber band. The elastic ring 21 can be bound to the outside of the handheld part of the B-ultrasound probe, which is convenient for temporarily fixing the probe after being sleeved. When rotation is needed, the entire sheath 2 can rotate together, or the probe can be rotated alone after stretching and opening the elastic ring 21, making it more convenient to use. Moreover, during the period without operation, the elastic ring 21 can limit the rotation of the probe and keep it stably sleeved to prevent the probe from falling. The front end of the elastic ring 21 extends a section of sheath, which is used to wrap a section of the B-ultrasound line closest to the surgeon's sterile hands, so as to avoid the doctor's hand accidentally touching the contaminated B-ultrasound line during the operation.

[0041] An anti-splash piece 22 is also connected to the outside of the sheath 2. The anti-splash piece 22 is also made of PVC film. The anti-splash piece 22 is a sheet-like structure arranged around the outer wall of the sheath 2, forming a skirt-like structure protection ring. The sheath 2 is fixedly connected to the bottom edge of the protective film 1. The anti-splash piece 22 and the protective film 1 are an integral structure. The annular width d of the anti-splash piece 22 is 5 cm.

[0042] The sheath 2 is connected and fixed to the protective film 1 through the anti-splash piece 22. The anti-splash piece 22 can block pollutants such as feces and bacteria splashed from the anus, so that the pollutants are blocked on the back of the anti-splash piece 22 outside the sheath 2. Through the combined barrier of the anti-splash piece 22 and the protective film 1, the direct pollution of pollutants in the rectum and the indirect pollution caused by aerosol dissemination are effectively reduced, the probability of the wound being infected is greatly reduced, and the pollution amount in the operating room can also be reduced.

[0043] The sampling piece 3 is a square thin sheet, made of PVC transparent thin sheet, and has a certain hardness, which can be easily torn and taken. A plurality of sampling pieces 3 are sequentially connected in the left-right direction to form an easy-to-tear strip. A perforation line 31 is provided between adjacent sampling pieces 3, and the sampling pieces 3 are connected through the perforation line 31.

[0044] An angle scale 4 is also provided at the bottom of the front surface of the protective film 1. The center of the angle scale 4 is the center of the sheath 2. The angle scale 4 is an angle marking line in the shape of a protractor. The bottom straight edge of the angle scale 4 overlaps with the bottom edge of the protective film 1. The interval angle between adjacent line segments of the angle scale 4 can be selected as 5°, which is convenient for doctors to accurately position the inserted probe.

[0045] The center of the angle scale 4 is on the axis of the sheath 2, and the axis of the sheath 2 is perpendicular to the plane where the protective film 1 is located. Such a perpendicular relationship is convenient for the sheath 2 to extend into the rectum for operation, and is also convenient for the angle scale 4 to guide the puncture needle to enter the needle and rotate the angle of the probe.

[0046] It should be noted that:

[0047] 1. The sheath 2 is a relatively long transparent rubber sleeve with elasticity and requires aseptic treatment. Its inner wall needs to be smooth to facilitate the rotation and direction adjustment of the probe inside the sheath 2. The rear end of the sheath 2 should be made of elastic material, the same as the condom material, and the diameter should be smaller to closely adhere to the scanning surface of the B-ultrasound probe, preventing the influence on the ultrasonic imaging quality due to insufficient fitting or the existence of air bubbles between the probe and the sheath. At the same time, the diameter of the front end of the sheath 2 should be larger to facilitate the sleeving and adjustment of B-ultrasound probes of different sizes for use. 2. The placement bag 11 does not need to be sticky, but it needs to maintain a certain distance from the puncture site of the operation to ensure that it can hold up and accommodate the patient's penis and scrotum to avoid the scrotum and scrotal prolapse from blocking the operation site. 3. In the past, when taking samples during surgery, additional tools were needed to scrape the specimens and then transfer them to containers such as test tubes and cups for temporary storage. During the transfer process, sample loss and contamination were likely to occur, and at the same time, the operation time was increased. This device is equipped with a sampling piece 3. When taking samples, the doctor can directly and conveniently scrape the sample at the tip of the puncture needle onto the sampling piece, without the need to scrape and transfer with other instruments, avoiding sample loss and contamination during the transfer process, shortening the operation time, and the easy-to-tear design enables the tissue sample to be torn off together with the sampling piece and immersed in the specimen fixing solution, and the sample always adheres to the sampling piece, which is also convenient for subsequent pathologists to search for and extract the sample.

[0048] When the present invention is in use, take out the protective film 1 in the sealed aseptic package, and then tear off the protective release paper of the adhesive film 13 to expose the adhesive film 13.

[0049] Attach the protective film 1 with the adhesive film 13 to the skin of the patient's disinfected operation area, ensure that the avoidance groove 12 fits with the inner sides of the legs, and then the entire protective film 1 covers and protects the patient's operation area. The sheath 2 is facing the patient's anus, the patient's penis is placed in the upper straight rod bag of the placement bag 11, and the scrotum is placed in the lower round bag of the placement bag 11 to ensure that the puncture area is completely exposed for convenient operation.

[0050] Insert the B-ultrasound probe into the sheath 2, and use the elastic ring 21 to hoop the handheld end of the probe. Then insert the probe covered with the sheath 2 into the patient's rectum, and place the splash-proof piece 22 around the anus to block the excrement. Subsequently, the operator first determines the target puncture area in the prostate through B-ultrasound scanning, then rotates and fixes the probe at the angle where the target area is located, and inserts the puncture needle along the scale line at the same angle as the probe plane under the guidance of the angle scale 4, so that the path of the puncture needle can be viewed in real time in the B-ultrasound image, and then puncture and sample the target area.

[0051] After taking out the sample, scrape the sample onto the sampling piece 3. Multiple samplings can be taken and all are placed on the sampling piece 3 in sequence. After the operation is completed, the doctor manually tears off the sampling piece with the tissue sample along the perforation line 31 and immerses it in the specimen fixing solution for submission for inspection. This operation is convenient, simplifies the specimen scraping and transfer process, and is not likely to cause specimen loss and contamination.

[0052] The front of this device refers to the side facing the doctor, and the back refers to the side in contact with the patient's skin; the upper side refers to the side close to the head, and the lower side refers to the side close to the operating table, that is, the standing position of the doctor during the operation is used as the up and down orientation. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0053] Although the specific embodiments of the present invention have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should all be covered by the scope protected by the claims of the present invention.
