Abstract
The utility model discloses an gas tightness hold mechanism of chamber mirror anastomat, including link rod sealing washer, sealed staple bolt and sleeve pipe sealing washer, the link rod sealing washer sets up between the articulated link rod and the link rod sleeve pipe of anastomat, sealed staple bolt sets up between the link rod inner core and the link rod shell of anastomat, sleeve pipe sealing washer sets up between the link rod inner core and the link rod sleeve pipe of anastomat. Compared with the prior art, the utility model, through the elastic construction setting of tertiary sealed leak protection, promoted the gas tightness of chamber mirror anastomat by a wide margin, can prevent chamber mirror anastomat basically and produce gas leakage, very big reduction the inflation volume when performing the operation, eliminated because of the big organ that exists of air flow shifts the potential safety hazard of performing the operation that causes, promoted the result of use of chamber mirror anastomat, improved the factor of safety of operation.
Description
Technical Field
The utility model belongs to the technical field of medical equipment, concretely relates to gas tightness hold mechanism of chamber mirror anastomat.
Background
The existing endoscope anastomat needs to be inflated during operation, for example, an abdominal minimally invasive surgery, the abdominal cavity needs to be inflated during the operation, the pressure in the cavity is maintained at a proper level so as to facilitate the operation, the existing endoscope anastomat achieves a certain air tightness effect through matching connection of all parts, but the air tightness is not ideal, the air pressure stability is poor, the inflation quantity during the operation is large for maintaining the pressure in the cavity, and the large inflation quantity during the operation can displace organs due to large air flow, so that the potential safety hazard of the operation exists.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the air tightness keeping mechanism capable of enabling the endoscope anastomat to have good air tightness is provided.
The technical scheme is as follows: in order to realize the above object, the utility model provides an gas tightness hold mechanism of chamber mirror anastomat, including link rod sealing washer, sealed staple bolt and sleeve pipe sealing washer, the link rod sealing washer sets up between the articulated link rod and the link rod sleeve pipe of anastomat, sealed staple bolt sets up between the link rod inner core and the link rod shell of anastomat, sleeve pipe sealing washer sets up between the link rod inner core and the link rod sleeve pipe of anastomat.
Furthermore, the connecting rod sealing ring is matched with the gap space between the hinged connecting rod and the connecting rod sleeve, the connecting rod sealing ring is clamped between the hinged connecting rod and the connecting rod sleeve, the connecting rod sealing ring has certain elastic telescopic performance, and the gap between the hinged connecting rod and the connecting rod sleeve can be well blocked by the connecting rod sealing ring, so that a good sealing effect is achieved.
Furthermore, the sealing hoop is matched with the gap space between the inner core of the link rod and the outer shell of the link rod, the sealing hoop is clamped between the inner core of the link rod and the outer shell of the link rod, the sealing hoop has certain elastic telescopic performance, and the gap between the inner core of the link rod and the outer shell of the link rod can be well blocked by utilizing the sealing hoop, so that a good sealing effect is achieved.
Furthermore, the sleeve sealing ring is matched with the gap space between the link rod inner core and the link rod sleeve, the sleeve sealing ring is clamped between the link rod inner core and the link rod sleeve, the sleeve sealing ring has certain elastic telescopic performance, and the sleeve sealing ring can be used for well blocking the gap between the link rod inner core and the link rod sleeve, so that a good sealing effect is achieved.
Has the advantages that: compared with the prior art, the utility model, through the elastic construction setting of tertiary sealed leak protection, promoted the gas tightness of chamber mirror anastomat by a wide margin, can prevent chamber mirror anastomat basically and produce gas leakage, very big reduction the inflation volume when performing the operation, eliminated because of the big organ that exists of air flow shifts the potential safety hazard of performing the operation that causes, promoted the result of use of chamber mirror anastomat, improved the factor of safety of operation.

Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in fig. 1 to 3, the endoscopic stapler includes a barrel 1 and a handle 2, the barrel 1 is composed of an articulated link 9, a link core 6, a link sleeve 8, a steering link 7 and a link housing 10, a link seal ring 4 is matched with and snapped between the articulated link 9 and the link sleeve 8, a seal hoop 3 is matched with and snapped within the gap spaces of the link core 6, the steering link 7 and the link housing 10, and a sleeve seal ring 5 is matched with and snapped between the link core 6 and the link sleeve 8.
Referring to fig. 1-3, when the endoscope anastomat is used in an operation, a part of a gun barrel 1 extends into an abdominal cavity in a patient, and due to a three-stage sealing structure formed by a sealing hoop 3, a link rod sealing ring 4 and a sleeve sealing ring 5, good air tightness is formed inside the gun barrel 1, so that air in the abdominal cavity of the patient cannot escape out of the gun barrel 1 through the gun barrel 1, the required intra-cavity pressure can be maintained in the abdominal cavity of the patient in the operation process, inflation is not needed, and the potential safety hazard of the operation caused by organ displacement due to large inflation air flow is eliminated.
