Embodiment 1

[0035] Example 1, such as figure 1 , figure 2 and image 3 Shown: a puncture device, including an outer sheath 1, and an inner cavity 12 is arranged in the outer sheath 1. During the operation, the puncture needle can be put into the inner cavity 12 first, and then the patient is punctured. After the puncture, The puncture needle is removed and placed into the endoscope. During operation, there will be stress in the vertical direction, which will easily cause the outer sheath 1 to slip off from the patient's body. For better fixation, an anti-slip portion 11 is provided outside the side wall of the outer sheath 1 . The anti-slip part 11 may include a plurality of anti-slip stripes, so that the outer sheath 1 is better fixed to the patient's body.

[0036] After the puncture, in order to maintain the air pressure balance of the patient's affected area and provide operation space for the operation, it is necessary to input airflow to the operation area on the patient's body....

Embodiment 2

[0043] Embodiment 2: The difference from Embodiment 1 is that the installation position of the heat fixing device 6 of the heating device is different. Such as Figure 4 As shown, in Embodiment 1, both the heat-fixing device 6 and the air-heating device 5 are integrated in the inner cavity 12. In this embodiment, the heat-fixing device 6 is separated and externally placed outside the trocar. heating structure. In actual use, the user can first contact the endoscope with the heat-fixing device 6 to achieve a rapid temperature rise, and then put the endoscope into the inner cavity 12 for operation after heating up, and the heat maintenance during the operation depends on the air-heating device 5.

Embodiment 3

[0044] Embodiment 3 differs from Embodiment 1 in that the structure of the switching device 7 is different. In this embodiment, the switching device 7 is a locking mechanism, and the switching device 7 and the outer sheath 1 are provided with matching threads. The heat-fixing device 6 is provided with matching slopes, the user twists the switching device 7, the switching device 7 starts to rotate, and changes the position in the vertical direction of the outer sheath 1, and under the resistance of the slopes, the heat-fixing device 6 moves in the horizontal direction The displacement, thereby changing the distance from the endoscope.

Abstract

The invention relates to the field of medical products, and aims to provide a puncture set and a heating device applicable to the puncture set. The heating device applicable to the puncture set comprises a heat source, a driving device, an air heating device and a solid heating device, wherein the driving device is used for driving the heat source to emit heat, the air heating device and the solid heating device are used for heating an endoscope, one end of the air heating device is connected with an air inlet of an outer sheath, the other end of the air heating device is connected with an inner cavity of the outer sheath, and the solid heating device comprises a contact part for contacting with the endoscope. The endoscope can be heated by the heating device without inserting the endoscope into the outer sheath or extracting the endoscope from the outer sheath, generation of fog shielding operation fields is avoided, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a heating device suitable for a trocar and a trocar. Background technique [0002] Trocars are common surgical medical devices, and are widely used in surgical operations such as abdominal surgery and thoracic surgery. A common puncture device, such as the structure disclosed in Chinese patent document CN 103284779 A, ​​includes an outer sheath, a puncture needle and an endoscope in the outer sheath. Because the human body has body temperature and the operating environment is humid, there is easy fog on the endoscope, which will affect the observation field of the endoscope and bring inconvenience to the operation. [0003] In order to remove the mist, there are also different technical solutions to improve the piercer structure. For example, the trocar disclosed by US Patent No. US4076018 has a heating coating on the endoscope to prevent fogging. Although this can achieve a ce...
