Abstract
The utility model relates to an electronic swing joint for chamber mirror, it includes swing head, base and locating lever group, when the locating lever group was in the same place with the swing head card, the swing head just was fixed. When the positioning rod group is separated from the swinging head, the swinging head can swing left and right by a certain angle under the action of external force; after the swing head swings to a proper angle, the positioning rod group can be clamped with the swing graph again under the action of the return spring. The swing head is installed at the front end of the base, and the positioning rod group is installed in the base. The positioning rod group comprises a sliding rod and a return spring, a tooth-shaped groove is formed in the front end of the sliding rod, and external tooth-shaped structures which are uniformly and circumferentially distributed are arranged at the rear end of the swinging head; the outer tooth-shaped structure can be inserted into the tooth-shaped groove, so that the swinging head is fixedly connected with the base.
Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically be a swing joint for electronic cavity mirror.
Background
An endoscopic stapler (an endoscopic cutting stapler and a disposable nail box) is one of important instruments for endoscopic surgery, replaces the traditional manual suture, utilizes titanium nails to break or inosculate tissues, is simple and rapid to operate, and greatly shortens the operation time. The endoscope anastomat ensures that the anastomosis with narrow surgical field and deeper part which is difficult to manually operate becomes easy, accurate, firm and reliable, and obviously reduces the incidence rate of anastomotic fistula.
The front end jaw of the endoscope linear anastomat is mostly designed in a variable angle mode, and the connection of the front end jaw and the rod body needs to adopt a movable joint mode. The design that can realize becoming the angle in the existing market has multiple form to satisfy the identical demand of special portion, alleviate doctor's the operation degree of difficulty, but mostly can't satisfy the angle locking function.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art not enough, the swing joint for electronic cavity mirror that provides, easy and simple to handle, can carry out the angle locking, make things convenient for doctor's operation.
In order to achieve the purpose, the utility model adopts the technical proposal that: a swing joint for an electric endoscope comprises a swing head, a base and a positioning rod group, wherein the swing head is installed at the front end of the base, and the positioning rod group is installed in the base; the positioning rod group comprises a sliding rod and a return spring, a tooth-shaped groove is formed in the front end of the sliding rod, and external tooth-shaped structures which are uniformly and circumferentially distributed are arranged at the rear end of the swinging head; the external tooth-shaped structure can be inserted into the tooth-shaped groove.
Furthermore, a front sliding groove, a middle groove and a rear sliding groove are arranged in the base, and a positioning step is arranged between the front sliding groove and the middle groove.
Furthermore, the swing head is also provided with a connecting hole, the front end of the base is provided with a connecting column, and the connecting column is sleeved in the connecting hole.
Furthermore, the sliding rod comprises an end head, a middle connecting rod and a tail rod, and a positioning boss is arranged at the rear part of the middle connecting rod; the reset spring is sleeved on the tail rod, and the reset spring is integrally positioned in the rear sliding groove.
Further, the distribution angle of the external tooth profile structure is 50-65 degrees.
Because of the application of above-mentioned technical scheme, compared with the prior art, the utility model has the following advantage:
the tooth-shaped groove is matched with the outer gear mechanism to realize the angle locking function; the sliding rod is pushed and pulled backwards, and the return spring is compressed, so that unlocking can be realized, and the operation is convenient; after the push-pull force disappears, the reset spring automatically pushes the sliding rod to move forward, and the locking is recovered.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic diagram of the appearance structure of the present invention;
fig. 2 is a partially enlarged schematic view of the present invention.
In the figure: 1. a swinging head; 1-1, connecting holes; 1-2, connecting blocks; 1-3, an external tooth profile structure; 2. a base; 2-1, connecting columns; 2-2, a front chute; 2-3, positioning a step; 2-4, a middle groove; 2-5, a rear sliding groove; 3. a slide bar; 3-1, tooth-shaped grooves; 3-2, end heads; 3-3, a middle connecting rod; 3-4, positioning a boss; 3-5, a tail rod; 4. a return spring.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 2, the swing joint for the electric endoscope comprises a swing head 1, a base 2 and a positioning rod group, wherein when the positioning rod group is clamped with the swing head 1, the swing head 1 is fixed. When the positioning rod group is separated from the swing head 1, the swing head 1 can swing left and right by a certain angle under the action of external force; when the swing head 1 swings to a proper angle, the positioning rod group is clamped with the swing rod 1 again under the action of the return spring 4.
To achieve the above purpose, the oscillating head 1 is installed at the front end of the base 2, and the set of positioning rods is installed in the base 2. The positioning rod group comprises a sliding rod 3 and a return spring 4, the front end of the sliding rod 3 is provided with a tooth-shaped groove 3-1,
the rear end of the swinging head 1 is provided with external tooth-shaped structures 1-3 which are uniformly and circumferentially distributed; the external tooth-shaped structure 1-3 can be inserted into the tooth-shaped groove 3-1, so that the swing head 1 is fixedly connected with the base 2.
A front sliding groove 2-2, a middle groove 2-4 and a rear sliding groove 2-5 are arranged in the base 2, and a positioning step 2-3 is arranged between the front sliding groove 2-2 and the middle groove 2-4. The positioning steps 2-3 are matched with the positioning bosses 3-4, so that the sliding rod 3 is prevented from being excessively advanced when the swing angle of the swing head 1 is too large, and a dead point is prevented.
The swing head 1 is also provided with a connecting hole 1-1, the front end of the base 2 is provided with a connecting column 2-1, and the connecting column 2-1 is sleeved in the connecting hole 1-1.
The sliding rod 3 comprises an end 3-2, a middle connecting rod 3-3 and a tail rod 3-5, and a positioning boss 3-4 is arranged at the rear part of the middle connecting rod 3-3; the return spring 4 is sleeved on the tail rod 3-5, and the whole return spring 4 is positioned in the rear chute 2-5.
