Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable ultrasound probe puncture holder. Background Technology

[0002] Interventional therapy is an emerging discipline that integrates imaging diagnosis and clinical treatment. It typically utilizes imaging equipment such as CT and ultrasound to guide and monitor the insertion of specific instruments, including needles, catheters, and other interventional devices, through natural orifices or tiny incisions in the body for minimally invasive treatment. Ultrasound-guided puncture is a commonly used interventional treatment method. It uses ultrasound to monitor and guide the needle through a living tissue sample to obtain cellular and pathological diagnostic data. In ultrasound-guided puncture procedures, coupling gel is applied to the puncture site, and then the needle insertion is guided and monitored by ultrasound equipment.

[0003] In clinical use, the ultrasound probe image, in conjunction with the ultrasound probe puncture frame, guides the puncture needle into the patient's body for interventional treatment. In recent years, with the advancement of ultrasound instrument performance, the improvement of puncture needles, and the accumulation of physician experience, ultrasound-guided puncture technology has become a very important diagnostic technique. When used, the puncture frame is fixed to the ultrasound probe and has a guide sheath for positioning the puncture needle. For example, Chinese invention patent CN116077151A discloses an ultrasound probe puncture frame, including a bracket (100), a first connector (110), a fixing part (200), and a guide needle sleeve (300). One end of the bracket (100) is connected to the fixing part (200) via the first connector (110), and the other end of the bracket (100) is detachably connected to the fixing part (200) via a snap-fit ​​component. The bracket (100) and the fixing part (200) are used together to place the ultrasound probe. The guide needle sleeve (300) is connected to the bracket (100) and is used to place puncture needles of different sizes. However, this ultrasound probe puncture frame is only suitable for installing a certain size of ultrasound probe, with a limited scope of application. In clinical use, hospitals need to purchase multiple ultrasound probe puncture frames of different sizes, resulting in relatively high costs, and the cleaning and disinfection costs are also not low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable ultrasound probe puncture holder. This adjustable ultrasound probe puncture holder can be used to install and fix ultrasound probes of different specifications, has a wide range of applications, and is easy to install. The technical solution adopted is as follows:

[0005] An adjustable ultrasound probe puncture frame includes a probe holder, a connecting seat, and a guide needle sleeve, with the guide needle sleeve mounted on the connecting seat. The probe holder comprises a fixed arm, two movable arms, and two locking seats. The fixed arm is mounted on the rear side of the connecting seat. The two movable arms are arranged side-by-side on the rear side of the fixed arm. The front end of the movable arm on the left is hinged to the left end of the fixed arm, and the front end of the movable arm on the right is connected to the right end of the fixed arm. The lengths of both movable arms are adjustable. Two locking seats are respectively located on the rear ends of the two movable arms, and the two locking seats are connected by a locking structure.

[0006] During surgery, the probe holder is used to mount and fix the ultrasound probe, and the guide needle sleeve is used to position the puncture needle. Through the coordination of the ultrasound probe image and the ultrasound probe puncture holder, the puncture needle can be guided into the patient's body for interventional treatment. When it is necessary to mount and fix the probe holder to the ultrasound probe, first, the locking structure can be released and the two locking seats separated. Then, the fixed arm of the probe holder is placed on the front side of the ultrasound probe, and the two movable arms are swung around their front hinges until they are close to the side wall of the ultrasound probe. The locking structure then connects the two locking seats together, so that the ultrasound probe is in the rectangular mounting opening formed by the fixed arm, the two movable arms, and the two locking seats. This facilitates the mounting of the probe holder to the ultrasound probe. Furthermore, by adjusting the length of the two movable arms, the size of the mounting opening of the probe holder can be adjusted to accommodate different sizes of ultrasound probes, thus broadening its applicability.

The front connecting arm of the movable arm on the right is connected to the right end of the fixed arm. The front connecting arm has a sliding groove running in a front-to-back direction. The rear end of the rear connecting arm is connected to the locking seat. The front end of the rear connecting arm has a slider, which is located in the sliding groove and slides in cooperation with it. A positioning mechanism is provided between the slider and the sliding groove. When it is necessary to adjust the length of the movable arm, the relative position of the front and rear connecting arms in the front-to-back direction can be adjusted by sliding the slider forward or backward along the sliding groove. The positioning mechanism positions the slider, thereby facilitating the adjustment of the length of the movable arm.

[0008] As a further preferred embodiment of this utility model, the positioning mechanism includes at least one first ball-head plunger, each of which is mounted on the slider. The ball head of the first ball-head plunger is in close contact with the corresponding inner wall of the sliding groove. The inner wall of the sliding groove is provided with a plurality of first locking grooves that can engage with the ball head of the first ball-head plunger. Thus, the slider can be positioned by engaging the ball head of the ball-head plunger with different first locking grooves.

[0009] As a further preferred embodiment of this utility model, the positioning mechanism includes at least one elastic locking block, each elastic locking block being mounted on the slider, and the elastic locking block being in close contact with the corresponding inner wall of the sliding groove; the inner wall of the sliding groove is provided with multiple locking grooves capable of engaging with the elastic locking blocks. Specifically, the elastic locking blocks can be made of elastic plastic (such as PE) or highly elastic rubber. Thus, by enabling the elastic locking blocks to engage with different locking grooves, the positioning of the slider can be achieved.

[0010] As a preferred embodiment of this utility model, the locking structure includes a locking screw and two connecting screw holes. The two connecting screw holes are respectively opened on the two locking seats and are positioned relatively aligned. The screw rod passes through the two connecting screw holes in sequence and engages with them. When it is necessary to connect and lock the two locking seats, the two locking seats can be brought together and the two connecting screw holes aligned. Then, the screw rod passes through the two connecting screw holes in sequence and engages with them to connect the two locking seats.

[0011] In a preferred embodiment of this invention, the guide needle sleeve is gradually tilted downwards from back to front. This facilitates guiding the puncture needle into the patient's body for interventional treatment.

[0012] As a further preferred embodiment of this utility model, the first end of the guide needle sleeve is hinged to the connecting seat via a second pin oriented laterally. The second end of the guide needle sleeve is fitted with a second ball-head plunger, the ball of which is in close contact with the surface of the connecting seat. The surface of the connecting seat is provided with a plurality of second locking grooves arranged sequentially around the second pin, each capable of engaging with the ball of the second ball-head plunger. With this structure, the guide needle sleeve can be swung up and down around the second pin to adjust the puncture angle of the puncture needle, and the guide needle sleeve can be positioned by engaging with different first locking grooves using the ball of the plunger. This design is convenient to operate.

[0013] As a preferred embodiment of this utility model, the probe holder, connecting seat, and guide needle sleeve are all made of medical-grade plastic, resulting in a lower overall cost.

[0014] The aforementioned guide needle sleeve can adopt an existing conventional structure, as can be found in the specification of Chinese invention patent with publication number "CN116077151A" and patent title "An Ultrasonic Probe Puncture Frame". Generally, the adjustable ultrasonic probe puncture frame is also provided with a locking control mechanism for controlling whether the guide needle sleeve locks the puncture needle inside.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This adjustable ultrasound probe puncture holder allows for convenient mounting of the probe holder onto the ultrasound probe through the cooperation of a fixed arm, two movable arms, two locking seats, and a locking structure. Furthermore, the mounting opening size of the probe holder can be adjusted by changing the length of the movable arms, making it suitable for mounting on ultrasound probes of different specifications and thus having a wider range of applications.
