Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for prostate puncture. Background Art

[0002] Prostate puncture has become the gold standard for prostate diagnosis. Prostate puncture is mainly used for patients with elevated prostate-specific antigen or suspicious nodules felt in the prostate. The purpose of puncture is to extract prostate specimens for pathological section to further clarify whether there are lesions such as prostate cancer. Prostate biopsy can generally be performed under local anesthesia. If the patient needs to undergo painless surgery, intravenous anesthesia can also be given. The puncture methods include transrectal and transperineal methods. Now, most prostate punctures are performed under the guidance of color Doppler ultrasound, or in hospitals with conditions, prostate biopsy can be performed under the guidance of the fusion of magnetic resonance imaging and color Doppler ultrasound.

[0003] At present, there are two prostate puncture methods, one is transrectal prostate puncture and the other is transperineal prostate puncture. During the prostate puncture process, it is necessary to expose the surgical field to the greatest extent. The traditional method is to hold the patient's penis and testicles with both hands and lift them upward. However, during the traditional clinical puncture process, the patient's body position is not fixed by an external brace. Some patients have a low pain threshold and may change their body position or shake due to pain during the puncture process, which will seriously affect the doctor's operation. Therefore, a device is needed to assist the prostate puncture surgery.

[0004] In the prior art, in order to fully expose the surgical field in front of the doctor, generally, a gauze is used to fix the patient's penis and testicles, lift them upward, and then fix the gauze to the bed body or the patient's body. This auxiliary method is cumbersome and has a poor fixation effect. When the patient shakes the body due to pain, the gauze is extremely easy to deform and cannot achieve the fixation effect.

[0026] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0027] Embodiment 1

[0028] The present invention provides a puncture assistance device, and the assistance device is installed on the brackets on both sides of the hospital bed body. The specific structure is as Figure 1 shown. The puncture assistance device includes a connecting rod 2 connected to the brackets of the hospital bed body, specifically, a first connecting rod 21 and a second connecting rod 22 respectively connected to the brackets on both sides of the hospital bed body. A sliding connection is provided between the first connecting rod 21 and the second connecting rod 22 with an adjusting cross beam 9. A connecting sleeve 5 is sleeved on the outer wall of the adjusting cross beam 9. Elastic connecting bands 3 are sleeved on both ends of the outer wall of the connecting sleeve 5. One end of the elastic connecting band 3 away from the connecting sleeve 5 is detachably connected with a binding net pocket 1.

[0029] Specifically: as Figure 3 shown in the structural schematic view of the adjusting cross beam, two adjusting cross beams 9 are provided, namely a first adjusting cross beam 91 and a second adjusting cross beam 92. And as Figure 1 shown, a first connecting ring 12 and a second connecting ring 14 are respectively slidably arranged on the outer walls of the first connecting rod 21 and the second connecting rod 22. Again, as Figure 3 shown, one end of the first adjusting cross beam 91 is fixedly installed on the radial outer wall of the first connecting ring 12, and one end of the second adjusting cross beam 92 is fixedly installed on the radial outer wall of the second connecting ring 14. And the end of the first adjusting cross beam 91 away from the first connecting ring 12 is misaligned with the end of the second adjusting cross beam 92 away from the second connecting ring 14 and is sleeved together through the connecting sleeve 5. Among them, the inner walls of the first connecting ring 12 and the second connecting ring 14 are respectively in sliding fit with the outer walls of the first connecting rod 21 and the second connecting rod 22.

[0030] In this embodiment, as Figure 2As shown, a first limit pin 10 is provided on the first connecting ring 12. The tip of the first limit pin 10 faces the first connecting rod 21, and a first limit hole adapted to the tip of the first limit pin is provided on the first connecting rod 21. The same applies to the second connecting ring 14 and the second connecting rod, that is, a second limit pin is provided on the second connecting ring, the tip of the second limit pin faces the second connecting rod, and a second limit hole adapted to the tip of the second limit pin is provided on the second connecting rod. Among them, the tips of the first limit pin and the second limit pin are both set as spherical structures. By inserting the tips of the first limit pin and the second limit pin into the first limit hole and the second limit hole respectively, the fixation of the first connecting ring and the second connecting ring can be realized, and then the height adjustment of the adjusting cross beam 9 (including the first adjusting cross beam 91 and the second adjusting cross beam 92) and the connecting sleeve 5 can be realized. By sliding and adjusting the height of the connecting sleeve 5, the tension of the elastic connecting band 3 can be changed, so as to facilitate adjustment according to the positions of the patient's testicles and penis and improve the scope of application. In another embodiment, as Figure 2 shown, an elastic member 11 for pressing the first limit pin 10 is fixedly connected to the inner wall of the first connecting ring 12. The elastic member 11 is a common spring. Specifically, one end of the elastic member 11 is fixedly connected to the inner wall of the first connecting ring 12, and the other end is fixedly connected to one end (away from the tip) of the first limit pin 10. By the elastic force of the elastic member 11 to push the first limit pin 10 in real time, the stability of the fixation of the first connecting ring 12 can be effectively improved. The second connecting ring is set in the same way and will not be elaborated here.

[0031] In this embodiment, as Figure 1 shown in or 3, on both sides of the elastic connecting band 3 sleeved on both ends of the outer wall of the connecting sleeve 5, and a blocking ring 4 is fixedly provided on the connecting sleeve 5. The height of the blocking ring 4 is greater than the thickness of the side wall of the elastic connecting band 3. The blocking ring 4 can limit the displacement of the elastic connecting band 3 in the horizontal direction and prevent the elastic connecting band 3 from sliding along the outer wall of the connecting sleeve 5 during the puncture operation. After the blocking ring 4 is provided, the stability of the auxiliary device during the puncture operation can be greatly improved.

[0032] In this embodiment, as Figure 4 shown, a connecting member 13 is fixedly connected to the outer wall of the connecting sleeve 5, and a limit card block 6 is fixedly connected to the connecting member. The connecting member 13 can be a common cloth strip, which is used to prevent the limit card block 6 from being lost as much as possible. A magnet is embedded in the limit card block 6, and a groove matching the limit card block 6 is provided on the connecting sleeve 5; at the same time, as Figure 3As shown in the figure, a number of limiting accommodation parts for the limiting block 6 to engage are provided on the outer walls of the first adjusting cross beam 91 and the second adjusting cross beam 92. There are multiple limiting accommodation parts, and the multiple limiting accommodation parts are evenly distributed along the outer walls of the first adjusting cross beam 91 and the second adjusting cross beam 92, which can increase the range of sliding adjustment of the connecting sleeve 5. Moreover, the materials of the first adjusting cross beam 91 and the second adjusting cross beam 92 are preferably martensitic stainless steel that can be attracted by a magnet, and the engagement between the limiting block 6 and the limiting accommodation part can be facilitated by magnetic force. Specifically: the fixing of the connecting sleeve 5 can be realized through the engagement between the limiting block 6 and the limiting accommodation part. During the puncture operation, according to the actual position of the patient, the position of the connecting sleeve 5 needs to be slid and adjusted. At this time, the limiting block 6 is toggled until the limiting block 6 is separated from the adjusting cross beam 9 (including the first adjusting cross beam 91 and the second adjusting cross beam 92), and then the connecting sleeve 5 is slid to the required position, and the limiting block 6 is engaged with the limiting accommodation part again to realize the fixing of the connecting sleeve 5. When the patient is inconvenient to move after anesthesia, the connecting sleeve 5 can be adjusted according to the position of the patient lying on the hospital bed, and the position of the binding mesh bag 1 is changed, further improving the convenience of use.

[0033] In this embodiment, in order to facilitate the fixing of the connecting rod 2 and the hospital bed body bracket, as Figure 1 shown, a first elastic clamping plate 7 is fixedly connected to the bottom end of the first connecting rod 21, and a second elastic clamping plate is fixedly connected to the bottom end of the second connecting rod 22; the shapes of the first elastic clamping plate 7 and the second elastic clamping plate can be determined according to the cross-sectional shape of the hospital bed body bracket. In this embodiment, to adapt to a hospital bed with a circular cross-section of the bed body bracket, the first elastic clamping plate 7 and the second elastic clamping plate are selected to be of an arc structure, and elastic anti-slip layers 8 are fixedly connected to the inner walls of the first elastic clamping plate 7 and the second elastic clamping plate. The elastic anti-slip layer 8 is a common anti-slip rubber, which improves the stability of the connection between the connecting rod 2 and the hospital bed. Moreover, elastic openings are provided at the bottoms of the first elastic clamping plate 7 and the second elastic clamping plate. By bringing the opening close to the hospital bed body bracket and pressing until the bed bracket slides into the inner cavities of the first elastic clamping plate 7 and the second elastic clamping plate, the fixing with the hospital bed body bracket is realized through the elastic force of the first elastic clamping plate 7 and the second elastic clamping plate.

[0034] In this embodiment, a reinforcing laminate is sewn at the edge position of the binding mesh bag, and a number of ventilation holes are provided on the inner wall of the binding mesh bag; specifically: the binding mesh bag 1 is a woven mesh bag made of elastic yarn. Using soft-textured yarn can improve safety when holding the penis and testicles, and a reinforcing laminate is sewn at the edge position of the binding mesh bag 1. The reinforcing laminate can be made by folding and sewing the edge of the binding mesh bag 1, which can improve the strength of the edge of the binding mesh bag 1.

[0035] The specific usage method of a puncture-assisted device provided by the present utility model during the prostate puncture operation is as follows:

[0036] During the prostate puncture operation, the first connecting rod 21 and the second connecting rod 22 are first fixed to the bed, and then the patient's testicles and penis are supported by the restraint net bag 1. The detection end of the rectal probe is disinfected and lubricated. Finally, the probe is inserted through the anus and the puncture needle is inserted into the prostate puncture point. The prostate is positioned by the rectal probe to complete the puncture operation. During this process, the penis and testicles are supported by the restraint net bag 1, providing medical staff with good operation and visual space. Compared with the prior art of temporarily using gauze to fix the penis and testicles, the operation is convenient, and after replacing the restraint net bag 1, the device can be reused after disinfection.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
