Description

Technical Field

[0001] This application relates to puncture medical devices, and more specifically, to a probe holder and a transperineal puncture guide device using the probe holder. Background Technology

[0002] Prostate biopsy is the ultimate standard and best diagnostic method for prostate cancer. There are generally two approaches to performing a prostate biopsy: transperineal and transrectal. Transrectal biopsy requires a pre-operative enema and is prone to post-operative bleeding and infection of the rectal mucosa. Transperineal biopsy, due to its higher safety, greater ability to detect early-stage tumors, and reduced post-operative adverse reactions, is increasingly being used by more medical institutions.

[0003] During a transperineal prostate biopsy, an intraperineal ultrasound probe is used in conjunction with a puncture device. The tip of the device is placed close to the patient's perineum, and a biopsy needle is inserted into the prostate gland through the groove on the device. However, there is currently no standardized transperineal ultrasound probes from different manufacturers. Different probes vary in diameter (16-20mm) and shape, requiring multiple transperineal puncture guidance devices to be used with corresponding probes for stable and accurate guidance, thus increasing both production and usage costs. Therefore, a universal puncture guidance device compatible with multiple ultrasound probes is needed. Utility Model Content

The front and rear ends of the adapter block are respectively provided with a first limiting protrusion and a second limiting protrusion, which are inserted into the first mounting hole and the second mounting hole. The lower surfaces of the first and second limiting protrusions are respectively provided with an adapter positioning structure adapted to the positioning structure of the ultrasonic probe surface, and a first arc-shaped surface and a second enclosing arc-shaped surface adapted to the ultrasonic probe surface formed on both sides of the adapter positioning structure.

[0008] According to one embodiment of the probe mounting base described in the first aspect of this application, a guide groove extending from one side to the other is provided at the position between the first mounting hole and the second mounting hole in the axial direction of the base body, and a guide protrusion is provided at the position between the first limiting protrusion and the second limiting protrusion in the axial direction of the adapter block, which is inserted into the guide groove.

[0009] In one embodiment of the probe mounting base according to the first aspect of this application, a first guide slope is formed at the bottom of the inlet end of the first mounting hole and the second mounting hole, and a second guide slope is formed at the bottom of the outer end of the first limiting protrusion and the second protrusion.

[0010] In one embodiment of the probe mounting base according to the first aspect of this application, the adapter block is connected and fixed to the base body by a detachable elastic fastening structure.

[0011] According to one embodiment of the probe fixing base described in the first aspect of this application, the front end and rear end of the adapter block opposite to the first limiting protrusion and the second limiting protrusion are respectively provided with a first elastic cantilever and a second elastic cantilever, and a first buckle and a second buckle are respectively provided at the ends of the first elastic cantilever and the second elastic cantilever. A first buckle groove and a second buckle groove are respectively formed in front of the first mounting hole and behind the second mounting hole on the base body. After the first limiting protrusion and the second limiting protrusion of the adapter block are inserted into the first mounting hole and the second mounting hole respectively, the first buckle and the second buckle are engaged with the first buckle groove and the second buckle groove respectively.

Simultaneously, the adapter positioning structure on the lower surface of the adapter block inserted into the holder cooperates with the positioning structure on the surface of the ultrasound probe to prevent rotation and limit movement. Furthermore, the first and second wrapping arc surfaces on the lower surface of the adapter block are pressed tightly against the surface of the ultrasound probe, thus ensuring the probe holder is stably installed on the ultrasound probe. By replacing the adapter blocks with those compatible with different probe models, the probe holder can be installed and fixed on different models of ultrasound probes. This allows the transperineal puncture guide device using this probe holder to guide biopsy needles for puncture biopsy with different models of ultrasound probes, achieving a universal compatibility function.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.

[0025] Figure 1 A schematic diagram of a transperineal puncture guide device 100, according to an embodiment of this application, is shown mounted on an ultrasound probe 200. See also Figure 1 As shown, the transperineal puncture guiding device 100 includes a probe holder 1 and a puncture guiding assembly 2. The probe holder 1 is fitted and fixed to the ultrasound probe 200. The puncture guiding assembly 2 is mounted on the probe holder 1 and provides multiple needle grooves to guide the puncture needle for biopsy puncture. The specific structure and implementation of the puncture guiding assembly 2 are prior art and will not be described in detail in this application. The main improvement of this application is the design of a universal probe holder 1, which can be adapted to different models of ultrasound probes 200.

[0026] See Figure 2 and Figure 3 As shown, a probe holder 1 according to an embodiment of this application includes a base 11, an adapter block 12, a first locking member 13, and a second locking member 14. The base 11 is fitted onto the surface of an ultrasonic probe 200 and has a first arm 111 and a second arm 112 disposed opposite to each other. The first arm 111 and the second arm 112 can hold the ultrasonic probe 200 tightly from both sides. The first locking member 13 is connected to the lower ends of the first arm 111 and the second arm 112 to lock the first arm 111 and the second arm 112. The adapter block 12 is detachably inserted into the base 11 from the side where the second arm 112 is located. The lower surface of the portion of the adapter block 12 inserted into the base 11 is provided with an adapter positioning structure 123 adapted to the positioning structure on the surface of the ultrasonic probe 2000, and a first wrapping arc surface 124a and a second wrapping arc surface 124b adapted to the surface of the ultrasonic probe formed on both sides of the adapter positioning structure 123. When the first arm 111 and the second arm 112 grip the ultrasound probe 200 and lock it in place with the first locking member 13, the first wrapping arc surface 124a and the second wrapping arc surface 124b adhere to the surface of the ultrasound probe, and together with the first arm 111 and the second arm 112, fix the entire probe holder 1 to the ultrasound probe 200. According to this embodiment of the present application, the probe holder 1 can be provided with multiple selectable adapter blocks 12. Each adapter block 12 can be provided with an adapter positioning structure 123 adapted to different ultrasound probes 200, as well as a first wrapping arc surface 124a and a second wrapping arc surface 124b. Thus, by replacing different adapter blocks 12, different models of ultrasound probes 200 can be adapted for installation and fixation. The upper part of the seat body 11 is also provided with an installation structure for mounting the puncture guide assembly 2. The second locking member 14 is located on the other side of the seat body 11 and is used to lock the puncture guide assembly 2 onto the seat body 11 and prevent interference with the replacement of the adapter blocks 12.

[0027] See details Figure 3 and Figure 4As shown, a first mounting hole 113a and a second mounting hole 113b are respectively provided at the front and rear of the first arm 111 and the second arm 112 on the axial direction of the base 11 (i.e., the axial direction of the ultrasonic probe 200). Both the first mounting hole 113a and the second mounting hole 113b extend from the side of the base 11 closest to the second arm 112 towards the side closest to the first arm 111. A guide groove 114 extending from one side to the other is provided between the first mounting hole 113a and the second mounting hole 113b on the axial direction of the base 11. Correspondingly, a first limiting protrusion 121a and a second limiting protrusion 121b are respectively provided at the front and rear ends of the adapter block 12 on the axial direction, which are inserted into the first mounting hole 113a and the second mounting hole 113b on the base 11. A guide protrusion 122 is provided at the position between the first limiting protrusion 121a and the second limiting protrusion 121b on the axial direction of the adapter block 12, which is inserted into the guide groove 114 on the base 11. The lower surfaces of the first limiting protrusion 121a and the second limiting protrusion 121b are respectively provided with an adaptation positioning structure 123 that is adapted to the positioning structure of the ultrasonic probe surface, and a first arc-shaped surface 124a and a second enclosing arc-shaped surface 124b formed on both sides of the adaptation positioning structure 123 that are adapted to the ultrasonic probe surface. The positioning structure on the surface of the ultrasonic probe 200 may be a positioning boss, a positioning groove, etc., and the adaptation positioning structure 123 on the lower surface of the first limiting protrusion 121a and the second limiting protrusion 121b may be a matching positioning groove, a positioning boss, etc.

[0028] See further Figure 5 As shown, the bottom of the inlet end of the first mounting hole 113a and the second mounting hole 113b forms a first guide slope 1131, and the bottom of the outer end of the first limiting protrusion 121a and the second limiting protrusion 121b forms a second guide slope 1211. When the first limiting protrusion 121a and the second limiting protrusion 121b of the adapter block 12 are aligned with the first mounting hole 113a and the second mounting hole 113b of the base 11, the second guide slope 1211 at the outer end of the first limiting protrusion 121a and the second limiting protrusion 121b moves along the first guide slope 1131 at the inlet end of the first mounting hole 113a and the second mounting hole 113b, guiding the first limiting protrusion 121a and the second limiting protrusion 121b into the first mounting hole 113a and the second mounting hole 113b, while the first guide protrusion 122 is inserted into the corresponding guide groove 114.

[0029] After the adapter block 12 is inserted into the base 11, the adapter block 12 can be connected and fixed to the base 11 through a detachable elastic fastening structure. Thus, by aligning the adapter positioning structure 123 on the lower surface of the first limiting protrusion 121a and the second limiting protrusion 121b at both ends of the adapter block 12 with the positioning structure on the surface of the ultrasonic probe, and then by clamping the first arm 111 and the second arm 112 from both sides to lock the ultrasonic probe 200, so that the first wrapping arc surface 124a and the second wrapping arc surface 124b on the lower surface of the first limiting protrusion 121a and the second limiting protrusion 121b are in close contact with the surface of the ultrasonic probe 200, the probe fixing base 1 can be securely installed on the ultrasonic probe 200. (See [reference]). Figure 6 As shown.

[0030] See also Figure 3 As shown, the adapter block 12, on the side opposite to the first limiting protrusion 121a and the second limiting protrusion 121b, has a first elastic cantilever 125a and a second elastic cantilever 125b at its front and rear ends, respectively, and a first fastener 126a and a second fastener 126b at their ends. Correspondingly, see [reference needed]. Figure 4 As shown, a first latching groove 115a and a second latching groove 115b are formed in front of the first mounting hole 131a and behind the second mounting hole 131b, respectively, on the base 11. After the first limiting protrusion 121a and the second limiting protrusion 121b of the adapter block 12 are inserted into the first mounting hole 113a and the second mounting hole 113b respectively, the first latching position 126a and the second latching position 126b are engaged with the first latching groove 115a and the second latching groove 115b, respectively, fixing the adapter block 12 inside the base 11. See also... Figure 3 As shown, the first elastic cantilever 125a and the second elastic cantilever 125b are respectively provided with a first handhold 127a and a second handhold 127b on their opposite outer sides. By holding the first handhold 127a and the second handhold 127b and pressing them inward, the first buckle 126a and the second buckle 126b can be engaged or disengaged from the first buckle groove 115a and the second buckle groove 115b, respectively. The adapter block 12 is connected to the base body 11 through this detachable elastic fastening structure, which allows for easy replacement of different adapter blocks 12 to adapt to different models of ultrasonic probes 200.

[0031] See further Figure 3 Combination Figure 6As shown, the first locking member 13 for locking the first arm 111 and the second arm 112 includes a locking stud 131 and a locking nut 132. The lower end of the first arm 111 has a first connecting portion 1111, on which a connecting shaft 1112 is provided. The lower end of the second arm 112 has a second connecting portion 1121, which has a limiting U-shaped groove 1122. One end of the locking stud 131 has a connecting hole 1311 with an opening 1312 formed on the outside of the hole. This end of the locking stud 131 is hooked onto the connecting shaft 1112 of the first connecting portion 1111 through the connecting hole 1311 with the opening 1312, and is rotatably connected to the lower end of the first arm 111. The other end of the locking stud 131 passes through the limiting U-shaped groove 1122 in the second connecting portion 1121 at the lower end of the second arm 112 and is threadedly connected to the locking nut 132. Tighten the locking nut 132 along the locking stud 131 to press against the second connecting part 1121, and the lower ends of the first arm 111 and the second arm 112 will be locked, so that the first arm 111 and the second arm 112 hold the ultrasonic probe 200 tightly.

[0032] See further Figure 3 As shown, the second locking member 14 for locking the puncture guide assembly 2 includes an L-shaped mounting base 141 and a locking screw 142. The L-shaped mounting base 141 is located on the opposite side of the base body 11 opposite to the adapter block 12, and has an internal threaded hole 1141. The locking screw 142 is locked into the internal threaded hole 1411 from the outside, so that it can abut against the puncture guide assembly 2 mounted on the base body 11.

[0033] The perineal puncture guiding device 100 according to the above embodiments of this application can guide biopsy needles for puncture biopsy with different models of ultrasound probes 200 by changing different adapter blocks 12 on the probe holder 1, achieving universal compatibility and reducing production and usage costs. For ease of use, various forms of markings can also be set on the adapter block 12 to indicate the model of the probe it is compatible with, making it convenient for users to select and use according to the probe.
