Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic probe auxiliary device for surgery. Background Art

[0002] The main feature of ultrasound interventional diagnosis and treatment is that various puncture biopsy, X-ray angiography, aspiration, intubation, drug injection and other operations can be completed under the monitoring or guidance of real-time ultrasound. During the ultrasound interventional diagnosis and treatment process, an ultrasound probe is required to guide the puncture and monitor the entire operation process in real time.

[0003] The ultrasound probe is a reusable medical device. In order to ensure a sterile surgical environment, a sterile protective cover is wrapped around the outside of the ultrasound probe to isolate the ultrasound probe from the skin, thereby avoiding cross infection of the ultrasound probe.

[0004] In the prior art, for example, a patent document with authorization publication number CN 216933265 U discloses a coupling agent integrated ultrasonic probe cover, which includes a cover body and a coupling agent bag, wherein: the cover body has a front end closed surface and a side wall surface, the coupling agent bag is arranged on the inner wall of the cover body, a weak opening is arranged on the coupling agent bag, and the coupling agent bag is filled with coupling agent.

[0005] The above disclosed coupling agent integrated ultrasound probe cover can isolate the ultrasound probe from the skin, thereby avoiding cross infection of the ultrasound probe, and can squeeze the coupling agent package to rupture the weak opening, and then allow a certain amount of coupling agent to be squeezed onto the ultrasound probe, which is convenient for operation.

[0006] However, when performing ultrasound detection during surgery, the side of the probe cover that contacts the skin also needs to be filled with sterile coupling agent or sterile saline, otherwise the image cannot be displayed normally. Therefore, during the operation, the ultrasound probe operator needs to hold the ultrasound probe in one hand and hold a sterile syringe in the other hand to spray saline on the patient's skin to achieve coupling with the contact surface. If the air is relatively dry, the sprayed saline will evaporate quickly, and it needs to be sprayed multiple times during the entire operation, which causes inconvenience to medical staff and may also cause certain interference to the operation process. Utility Model Content

[0007] The utility model provides an ultrasonic probe auxiliary device for surgery, and aims to solve the technical problem of enabling medical personnel to spray physiological saline on the skin on the outer contact surface of the probe cover to achieve coupling with the skin contact surface.

[0020] like Figure 1-5 As shown, an ultrasonic probe auxiliary device for surgery in the present application includes a sleeve body 1, a coupling agent capsule 2 and a spray component 3.

[0021] In this embodiment, reference Figure 1 and Figure 2 One end of the sleeve 1 is closed and the other end is provided with an opening. The sleeve 1 is made of transparent or translucent plastic material or rubber material, which can effectively isolate pollution and facilitate the position of the ultrasonic probe in the sleeve 1 and check whether the probe is coated with coupling agent. The closed end of the sleeve 1 is used to contact the head end of the ultrasonic probe and allow ultrasonic waves to pass through to achieve ultrasonic examination of the target part of the human body.

[0022] Specifically, the ultrasound probe extends into the sleeve 1 from the opening end of the sleeve 1, and the length of the sleeve 1 is 1.5-2 meters. The entire ultrasound probe and the probe connecting line can be installed in the sleeve 1, so that the parts that may contact the patient are isolated by the sleeve 1.

[0023] Furthermore, a tie rope 11 is provided on the edge of the open end of the sleeve 1, and the tie rope 11 can tighten the open end of the sleeve 1. Specifically, in this embodiment, the tie rope 11 is a rubber band; therefore, the open end of the sleeve 1 can be tightened by the tie rope 11, so that it can be tightened and connected to the probe connection line, reducing the possibility of the sleeve 1 slipping off the ultrasound probe.

[0024] In other embodiments, a movable ring is provided on the edge of the open end of the sleeve 1, and a notch is provided on the movable ring. The drawstring 11 can be slidably provided in the movable ring, and both ends of the drawstring 11 extend out of the movable ring from the notch. The open end of the sleeve 1 can be tightened through the two ends of the drawstring 11, and the two ends of the drawstring 11 can also be tied to the probe connecting line to reduce the possibility of the sleeve 1 slipping off the ultrasound probe.

[0025] Further, refer to Figure 1 A fixing belt 12 is arranged on the outer side of the bag body near the closed end. The fixing belt is an elastic belt, and Velcro is arranged on both sides of the fixing belt end, so that the fixing belt 12 can fit itself after being wrapped around the ultrasonic probe arranged on the inner side of the sleeve body 1. Therefore, the sleeve body 1 can be clamped and fixed on the ultrasonic probe, further reducing the possibility of the sleeve body 1 slipping off the ultrasonic probe.

[0026] In this embodiment, reference Figure 2 and Figure 4 The coupling agent capsule 2 is arranged on the inner side of the sleeve body 1 near the closed end, and a weak opening 21 is arranged on the coupling agent capsule 2, and the weak opening 21 faces the closed end of the sleeve body 1. Specifically, the weak opening 21 can be made by pressing or laser thinning, or sealed by tin foil after opening.

[0027] The coupling agent capsule 2 is filled with coupling agent. When the coupling agent capsule 2 is pressed hard, the weak opening 21 on the coupling agent capsule 2 is broken, so that the coupling agent in the coupling agent capsule 2 is squeezed out from the weak opening 21 and enters the space between the front of the ultrasonic probe and the closed end of the sleeve 1.

[0028] In addition, the coupling agent capsule 2 is arranged on the inner wall of the sleeve 1, so that after the coupling agent is extruded, the coupling agent capsule 2 will not affect the ultrasonic transmission and the use of the ultrasonic probe; and the weak opening 21 is toward the closed end of the sleeve 1, which is more conducive to the coupling agent being squeezed out from the weak opening 21 and entering the space between the front part of the ultrasonic probe and the closed end of the sleeve 1.

[0029] In this embodiment, reference Figure 1-3The spray assembly 3 is used to spray liquid toward the front end of the sleeve 1 that contacts the patient's skin. The spray assembly 3 includes a spray head 31, a liquid storage bag 32, an infusion tube 33, and a switch valve 34. The spray head 31 is arranged on the outside of the sleeve 1 near the closed end. The spray head 31 is connected to the liquid storage bag 32 through the infusion tube 33. The switch valve 34 is arranged at one end of the infusion tube 33 near the spray head 31. Through the switch valve 34, medical staff can spray physiological saline on the patient's skin as needed to achieve coupling with the skin contact surface.

[0030] Further, refer to Figure 1 The spray assembly 3 further includes a connector 35, through which the spray head 31 is detachably connected to the liquid storage bag 32. The connector 35 is disposed on the outer side of the sleeve body 1 near the opening end, and both ends are connected to the infusion tube 33. Through the connector 35, the liquid in the liquid storage bag 32 can be replaced after use, or the liquid storage bag 32 can be replaced with other liquids as needed, such as replacing disinfectant, etc., and the patient's skin can be disinfected by the disinfectant during the surgical operation, and the coupling with the skin contact surface can be achieved.

[0031] The connector 35 includes a female connector 351 and a male connector 352, wherein the male connector 352 can be inserted into the female connector 351 and threadedly connected with the female connector 351. Furthermore, a wing plate 353 is provided on the female connector 351, and the female connector 351 and the male connector 352 can be easily disassembled by pinching the wing plate 353.

[0032] Specifically, refer to Figure 5 The nozzle 31 is trapezoidal, and the small end of the nozzle 31 is connected to the infusion tube 33, and a plurality of water outlets 311 are evenly arranged on the large end of the nozzle 31. By evenly arranging a plurality of water outlets 311 on the large end of the nozzle 31, the sprayed liquid can be sprayed on the patient's skin more evenly, and a larger spraying range can also be obtained.

[0033] Specifically, refer to Figure 3 The switch valve 34 includes a valve body 341, a valve core 342 and a spring 343. Both ends of the valve body 341 are connected to the infusion tube 33. The valve core 342 and the spring 343 are arranged in the valve body 341, and both ends of the spring 343 are respectively connected to the valve core 342 and the valve body 341. Under the action of the spring 343, the valve core 342 can close the valve body 341.

[0034] A handle 344 is provided at one end of the valve core 342 away from the spring 343. The handle 344 can be extended out of the valve body 341, and a sealing ring 345 is provided on the valve body 341. The sealing ring 345 is sleeved on the handle 344. Pressing the handle 344 can drive the valve core 342 to move and compress the spring 343, so that the valve body 341 is connected.

[0035] Therefore, when the medical staff presses the handle 344, the valve body 341 can be connected, and then liquid can be sprayed onto the patient's skin as needed to achieve coupling with the skin contact surface or disinfect the skin contact surface. When the medical staff releases the pressing handle 344, under the action of the spring 343, the valve core 342 will move and actively close the valve body 341 to prevent the liquid in the liquid storage bag 32 from being sprayed unintentionally.

[0036] During use, the medical staff inserts the ultrasonic probe and the probe connecting line into the sleeve 1 through the open end of the sleeve 1, and tightens the open end of the sleeve 1 through the drawstring 11 provided at the open end of the sleeve 1, clamps and fixes it to the probe connecting line, and uses the fixing belt 12 provided on the sleeve 1 to fix the front end of the sleeve 1 to the ultrasonic probe, then connects the liquid storage bag 32 to the nozzle 31, and hangs the liquid storage bag 32 on the infusion stand, and presses the coupling agent capsule 2 hard to break the weak opening 21 on the coupling agent capsule 2, and the coupling agent in the coupling agent capsule 2 is squeezed out from the weak opening 21 and enters the space between the front part of the ultrasonic probe and the closed end of the sleeve 1, and finally presses the switch valve 34 to spray liquid toward the skin of the patient at the front end of the sleeve 1 to achieve coupling with the skin contact surface, or disinfect the skin contact surface, and then complete various puncture biopsy, X-ray angiography, suction, intubation, injection treatment and other operations under the monitoring or guidance of real-time ultrasound.

[0037] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present utility model should be within the protection scope of the present utility model.
