Box, handle, hanger and operation method thereof

Technical Field

The invention belongs to the technical field of medical equipment, and particularly relates to a box, a handle, a hanger and an operation method thereof.

Background

Benign Prostatic Hyperplasia (BPH) is one of the most common medical conditions affecting men, especially elderly men. The prostate gland continues to expand throughout the life of a person. In some men, the prostate capsule surrounding the prostate may prevent the prostate from further enlargement. This can cause the inner region of the prostate to squeeze the urethra. This pressure on the urethra increases the resistance to urine flow through the region of the urethra surrounded by the prostate. Thus, the bladder must exert more pressure to force urine through the increased urethral resistance. Chronic overexertion can lead to remodelling of the muscle wall of the bladder and becoming stiffer. This increased urethral resistance and increased urinary flow stiffness and hypertrophy of the bladder wall can lead to various Lower Urinary Tract Symptoms (LUTS), which can severely reduce the quality of life of the patient. These symptoms include weak or intermittent urine flow during urination, exertion during urination, hesitation before urination begins, feeling that the bladder is not completely empty even after urination, dribbling or leaking urine at the end of urination, and particularly increased frequency of urination at night and urgency. In order to treat the problem of prostatic hypertrophy, mechanical devices that facilitate surgery are designed to assist medical personnel.

Referring to fig. 27, a guide rail protrusion 1144 is disposed on the other surface of the unidirectional transmission assembly, and the guide rail protrusion 1144 is divided into three sections to push the wire actuating assembly 2131 and the needle actuating assembly 2132 of the actuating assembly one 213 and the actuating assembly two 214, respectively.

28-29, A wire slider 126 is movably mounted on the cover 123 by a spring five 124, and a needle slider 127 is movably mounted on the cover 123 by a spring six 125, when the cassette 200 is mounted on the handle 100, the wire actuating assembly 2131 is snapped onto the wire slider 126, the needle actuating assembly 2132 is snapped onto the needle slider 127, and with reference to FIGS. 17 and 30-31, a wheel actuator 122 is movably mounted on the handle housing, and rotation of the wheel actuator 122 can drive the implant positioning bumper 2145 out of the push rod mount 2141.

The three sections of the guide rail protrusion 1144 can drive the needle slider 127 and the wire slider 126 to move respectively, and drive the wheel actuator 122 to rotate, when the handle 108 is pressed down for the first time, the handle 108 drives the unidirectional transmission assembly to rotate, and then the guide rail protrusion 1144 pushes the needle slider 127 and the wire slider 126 to advance, so that the first actuation assembly 213 drives the clip push rod 207, the puncture needle 203 and the suture thread 202 to advance simultaneously, the clip push rod 207 pushes the front clip 201 to advance simultaneously, the safety button 104 moves along with the guide rail protrusion 1141, and then the handle 108 is restored to an open state; when the handle 108 is pressed for the second time, the handle 108 drives the unidirectional transmission component to rotate, and then the guide rail protrusion 1144 pushes the needle slider 127 and the wire slider 126 to retreat, so that the first actuation component 213 drives the puncture needle 203 to retreat, and simultaneously drives the suture thread 202 to tighten and drives the front clip 201 to expand; when the handle 108 is pressed for the third time, the guide rail protrusion 1144 drives the wheel actuator 122 to rotate, so that the second actuating component 214 drives the push rod 205 and the cutter 206 to move simultaneously, the cutter 206 retreats, the push rod 205 pushes the rear clip 204 to advance, and the rear clip 204 clamps the suture 202 and cuts off the suture 202, and the whole hanger is pulled out to be separated from the treatment state; when the handle portion 108 is depressed a fourth time, the cassette 200 is removed and the handle 100 is locked.

Under the cooperation of the unidirectional transmission assembly, the push-away protrusion 1143 and the elastic portion 1132, the transmission assembly can only perform unidirectional transmission, so that the operation is prevented from entering the next operation step or returning to the previous operation step incompletely, the operation is stopped in the incomplete process, the operation is continuously completed when the handle portion 108 is pressed down again, the operation is prevented from entering the next step when the handle portion 108 is pressed down next time after the operation is completely completed, that is, one action is prevented from entering the next action before the operation is not completed, and the situation of operation errors is avoided.

Meanwhile, the design of the handle 100 extremely simplifies the operation steps, only the handle part 108 is pressed four times, the whole device can automatically perform the operation of the whole operation process, and finally the handle 100 can be locked after the operation is finished, so that the working process of operators is greatly facilitated.

Further, the handle 100 is further provided with a limiting component for limiting the pop-up state of the handle portion 108, and when one working step is not completely completed, the handle portion 108 is not popped up, but is limited to the current position.
