Description

Technical Field

[0001] The utility model relates to the technical field of staplers, in particular to a battery center-of-gravity rear-mounted structure and an electric laparoscopic stapler thereof. Background Art

[0002] An electric laparoscopic stapler generally includes an actuator and a power supply located at the rear end for powering the actuator. A Chinese patent with application number CN202310394406.1 discloses an integrated enclosed waterproof battery pack for an electric stapler, which defines two groups of battery placement positions. Each battery placement position is provided with two batteries placed with positive and negative poles opposite to each other, and the lower ends of the two batteries arranged with positive and negative poles opposite to each other are connected in series. However, it can be seen from the accompanying drawings that the two batteries arranged in each battery placement position are arranged longitudinally. Because the actuator of the stapler is located at the front end of the power supply, and the actuator contains more components and is heavier, the two groups of batteries arranged longitudinally cannot balance the weight of the actuator, causing the stapler to tilt forward when the operator is operating it. It needs to be supported at all times to keep it balanced, which can easily cause fatigue to the operator and reduce the accuracy of the surgical operation. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0028] Example 1:

[0030] The battery assembly 2 includes a battery compartment 202 and a plurality of batteries 201 arranged in series within the battery compartment 202. The plurality of batteries 201 are arranged transversely and divided into at least two rows from front to back. In this embodiment, four transversely arranged batteries 201 are provided. To ensure the compactness of the overall structure of the stapler, the four batteries 201 are symmetrical in pairs and divided into two rows from front to back, thereby shifting the center of gravity of the stapler rearward.

The batteries 201 arranged horizontally from front to back can move the center of gravity of the stapler backward to put the stapler in a balanced state and prevent it from tilting forward, thereby reducing the surgeon's fatigue and improving operating efficiency and accuracy.

[0032] In some examples, a connecting piece is provided between two adjacent batteries 201 in the plurality of batteries 201. The connecting piece is in the form of a thin sheet and is used to connect the positive and negative electrodes of the two adjacent batteries 201.
