Problems solved by technology

Due to the different physiques of patients and the imperfection of existing equipment, normal saline needs to be injected multiple times for each single test, and the detection of mitral valve sealing during surgery often requires multiple times, which greatly increases the workload of medical staff. However, it affects the operation time, and the existing working method cannot recycle the residual self blood and injected saline in the heart, resulting in waste

Embodiment 1

[0037]A water injection system for valve regurgitation testing in mitral annuloplasty described in this embodiment includes a catheter and a water delivery component connected to one end of the catheter, wherein the water delivery component includes normal saline and provides pressure to pump the normal saline The supply part that enters the heart. In this embodiment, a syringe is used. The syringe is connected with a quantitative pump to provide the system with a controllable amount of physiological saline. A valve regurgitation test water injection system in mitral annuloplasty in the present invention also includes a water injection assembly 1 arranged at the other end of the catheter and inserted into the inner side of the heart valve. The water injection assembly 1 includes a casing 1 integrally connected with the catheter and The telescopic element arranged in the housing 1. Wherein the telescopic member is connected to the inner surface of the housing 1 through an arc-s...

Embodiment 2

[0042] The specific structure of the valve regurgitation test water injection system in the mitral annuloplasty described in this embodiment is basically the same as that of the valve regurgitation test water injection system in the mitral annuloplasty described in Embodiment 1, and it is different The difference is that a sealing sheet 107 is provided at the center of the arc-shaped elastic sheet 103, and the sealing sheet 107 can be fixed on the water blocking plate 401 through the support rod 108, and the circumference of the sealing sheet 107 is close to the middle of the arc-shaped elastic sheet 103 and shrinks. inside side of the place. The setting of the sealing sheet 107 further improves the sealing performance of the water injection assembly 1 in the system, thereby effectively avoiding liquid leakage in the water injection assembly 1 when the water delivery assembly is not working. In this embodiment, the free end of the housing 101 of the water injection assembly 1 ...

Embodiment 3

[0044] The specific structure of the valve regurgitation test water injection system in the mitral annuloplasty described in this embodiment is basically the same as that of the valve regurgitation test water injection system in the mitral annuloplasty described in Embodiment 1, and it is different The advantage is that the supply part that provides a controllable amount of physiological saline for this system adopts a one-way hand-held squeeze ball 6, and the physiological saline in the storage chamber 5 is continuously supplied to the water injection through the doctor's squeeze of the one-way hand-held squeeze ball 6 components and then injected into the heart. The liquid inlet end of the one-way hand-held squeeze ball 6 is also provided with a pressure relief pipe 8, and the pressure relief pipe 8 is provided with an elastic diaphragm 801, and the inner wall of the pressure relief pipe 8 is opposite to the elastic diaphragm 801. A limit block is arranged, The liquid outlet...

Abstract

The invention discloses a valve regurgitation test water injection system in mitral valve repair. The system comprises a conduit and a water delivery assembly connected to one end of the conduit, andalso comprises a water injection assembly arranged at the other end of the conduit. The water injection assembly comprises a shell and a telescopic piece movably arranged in the shell. The telescopicpiece is connected with the inner side face of the shell through an arc-shaped elastic piece; the arc-shaped elastic piece enables the telescopic piece to shrink into the shell in a tortoise-shell mode in a non-stretching state, and the arc-shaped elastic piece serves as a water conveying channel to enable the telescopic piece to be communicated with the conduit. A water blocking plate is arrangedat the end, which is connected with the arc-shaped elastic piece, in the telescopic piece, and a water blocking valve is arranged at the other end of the telescopic piece. An air bag is arranged on the circumference of the shell, and a liquid leakage pipeline is arranged at the water outlet end of the water injection assembly. The regurgitation test water injection system is simple in structure,continuous water supply to a heart can be achieved, and the mitral valve sealing condition can be detected under the condition that a machine is not removed.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a valve regurgitation test water injection system in mitral annuloplasty. Background technique [0002] In mitral valvuloplasty and replacement, it is necessary to judge the effect of heart valvuloplasty before the incision is sutured. Most of the existing evaluation methods are to inject a certain amount of normal saline into the heart with a syringe according to the patient's constitution to observe the closure of the mitral valve. . Due to the different physiques of patients and the imperfection of existing equipment, normal saline needs to be injected multiple times for each single test, and the detection of mitral valve sealing during surgery often requires multiple times, which greatly increases the workload of medical staff. However, the operation time is affected, and the existing working method cannot recycle the residual self blood in the heart...
