Embodiment 1

[0035] Embodiment 1: the following combination Figure 1-Figure 6 To illustrate this embodiment, this embodiment relates to a puncture positioning device, such as figure 1 As shown, it includes a puncture needle catheter 220, a base 300 and an adjustment base 400. The adjustment base 400 is installed on the base 300. The adjustment base 400 can be fixed on the base 300 or can be installed on the base 300 by rotation. The puncture needle catheter 220 Set through the adjustment seat 400 and the base 300, the puncture needle catheter 220 is slidably arranged on the adjustment seat 400 along the axis, and the puncture needle catheter 220 is provided with a needle passage 203 for positioning the puncture needle to pass through. The needle catheter 220 protrudes from a position close to the detection end of the ultrasonic probe 100 .

[0036] In this embodiment, the adjusting seat 400 is preferably rotatably installed on the base 300. The adjusting seat 400 is used to control the r...

Abstract

The utility model discloses a puncture positioning device, relates to a medical diagnosis instrument, and aims to solve the problem that a tumor incision edge position cannot be accurately and flexibly positioned in a cavity channel and anal canal puncture or low rectal cancer operation process. The device comprises a puncture needle catheter, a base and an adjusting base, the adjusting base is installed on the base, the puncture needle catheter penetrates through the adjusting base and the base, the puncture needle catheter is arranged on the adjusting base in a sliding mode along the axis, and a needle penetrating channel used for positioning a puncture needle to penetrate through is formed in the puncture needle catheter; and the positioning puncture needle extends out from a position, close to the detection end of the ultrasonic probe, of the puncture needle catheter. The puncture needle catheter is more flexible in the puncture or rectal cancer operation process, operation is more convenient, staining positioning or puncture of a tumor can be accurately achieved, especially, the low-margin position of the tumor is determined, a doctor can make a clear judgment according to the position of the tumor, the operation risk and difficulty are reduced. The invention plays an important role in judging whether the anus needs to be protected in a low rectal cancer operation.

Description

technical field [0001] The invention relates to a tumor puncture instrument, in particular to a puncture positioning device. Background technique [0002] At present, due to the lack of technology and instruments for precise positioning of tumor margins in the operation of low rectal cancer, tumor resection is performed based on the surgeon's clinical experience, which requires high requirements and is difficult for the surgeon, and cannot be determined Resection range and resection location, if the resection range is too large, the remaining normal bowel canal is too short to be anastomosed, and if the resection range is too small, it will make it difficult to completely remove the tumor and cause recurrence, etc., which will affect the prognosis. [0003] During the operation of the existing anal canal puncture instrument, the puncture device and the ultrasonic probe are fixed together. After the ultrasound probe is inserted from the rectum to find the location of the tum...
